  • VR & Hi-Res Audio: This is how you really hear

    The forgotten feeling: what VR glasses tell us about good sound

    Imagine you’re watching a video. Not on the TV, but as if you were in the middle of it. Everything around you is an image and it feels like you can walk through the scene. I’m talking about VR goggles, and to be honest, until recently this was more of a gimmick for me. The images were often blurred, pixelated – you could sense the potential, but it didn’t really blow you away. But then Meta Quest 3 came into play. And with it came a resolution that simply left me speechless. Suddenly the image was so incredibly sharp, so detailed, that I really felt like I was part of this other world.

    But the real kicker came when I took my own videos from my hard drive and created them with a special program called Owl3D for these glasses. I put them on and the moment the video started, I thought: “This is amazing! I’ll never look at a normal screen again!” The image was so lifelike, so tangible. And although it was already breathtaking, I instinctively felt: “If only the resolution was just a little bit better!” It’s hard to imagine how incredible it would look if it were absolutely perfectly sharp – simply stunning. It’s already great, you can see everything, it looks great, but that last little bit more pixels, that would be it!

    Why we talk about VR when it comes to good sound

    It is precisely this feeling, this intuitive understanding of “resolution” and what would constitute an even sharper image, that is the key to a realization that many of us have unfortunately lost in the field of audio. Because it’s exactly the same in the world of sound! The only difference is that hardly anyone today knows what “good” sounds like.

    We are surrounded by music. It’s playing on the radio, streaming on our smartphones, coming out of small Bluetooth speakers. And yes, it all sounds okay somehow. It’s as if we’ve been looking at the world through these slightly pixelated VR glasses for years. We no longer know what we’re missing. We have become accustomed to a lower sound resolution, to highly compressed formats in which countless nuances, tiny details and the natural spatiality are simply no longer there.

    Streaming with low resolution

    As with VR glasses, where you lack a little resolution to really feel the fine texture of a tree bark in the virtual forest or see the sparkle in the eyes of an avatar, we lack the sound pixels in the sound. We hear the song, yes. But do we also hear the subtle vibration of a guitar string, the delicate reverberation of a voice in the recording room, the exact position of each individual instrument on the virtual stage? Can we hear the “air” in the room where the drums were recorded? Quite often, unfortunately not.

    Rediscovering the lost dimension of music

    Hi-Res Audio or excellent vinyl playback are like those razor-sharp VR glasses that suddenly show you what is visually possible. They add the lost pixels of sound. Suddenly, a whole new dimension of music is revealed:

    • Spatiality: The band is no longer a flat carpet of sound in front of you, but spreads out in the room. You can clearly locate individual instruments, feel their exact position and their reverberation, as if you were sitting in the middle of a concert hall.
    • Subtlety and detail: You suddenly hear the sound of the singer’s breathing, the soft creaking of a chair in the studio, the plucking of the strings of an acoustic guitar – all these tiny details that make the listening experience incredibly vivid and real.
    • Dynamics: The music really “breathes”. Quiet passages are really whisper-quiet, loud explosions are powerful and clear without being unpleasant or overdriven. The entire emotional range of the recording is palpable.
    • Emotion: With all these additional sound pixels and details, the music becomes more emotional, more gripping, more real. You are no longer just a listener consuming a recording, but immersed in the experience and almost become part of it.

    Many of us listen to music today as if we were looking at a world-famous painting through a tiny, blurry cell phone camera. You get the idea that you recognize it. But then you suddenly find yourself standing in front of the original in the museum. The colors, the texture of the brushstrokes, the sheer size – it’s a completely different emotional experience, isn’t it? You didn’t know what you were missing until you saw the real thing.

    It’s the same with the sound. For a generation that grew up with compressed MP3 files and streaming in average quality, the full, unadulterated sound – as it was recorded back then, with a stable power supply and via analog mixing consoles directly to tape – may be a completely new sensation. It’s not just “better”, it’s fundamentally more. It is a deep immersion, a rediscovery of the music we love and the experience of emotions that were previously hidden.

    Take the plunge: recalibrate your ears

    Maybe it’s time to put on the “VR glasses” for your ears. Find a really good hi-res source, be it a streaming service that offers lossless playback, a well-recorded vinyl or a high-quality FLAC file. Listen to your favorite music – and let yourself be surprised. You might very well realize afterwards: “I never want to listen with less sound resolution again!”

  • Nerd-torial: The dithering dilemma

    Nerd-torial: The dithering dilemma – Why our ear sometimes beats theory

    Welcome back, dear audio nerds! In the last Nerd-torial, we introduced you to our high-precision vinyl recording process, from 32-bit integer recording with the RME ADI-2 Pro FS to the internal 64-bit float processing in Sound Forge Pro 15. We learned why this extreme computing accuracy is crucial to preserve the “aura” of our records without loss.

    But at the end of every mastering process is a tricky decision: reducing the bit depth for export. And this is where dithering comes into play – a technique that seems contradictory at first glance, but is essential for sound quality. And as we found out at Mother Earth Radio, it sometimes works differently than theory predicts.

    Dithering: The small noise that makes big differences

    Remember: our audio data is processed internally with an incredible 64-bit floating point. This is a dynamic range that is far beyond anything the human ear or even the best studio technology can capture. If we now reduce this data to 24 bits (the standard for Hi-Res FLAC) for export, quantization errors occur mathematically. These errors are not harmless rounding differences; they manifest themselves as unmusical, harsh distortions that can sound like digital “chirping” or “tearing off”, especially in quiet passages.

    Dithering is the solution: we add a tiny, random noise to the signal. This noise is so small that it is barely audible. But it has a magical effect: it randomizes the quantization errors and converts them into a much more pleasant, analogue-sounding noise. The result: a clearer, more detailed and more natural sound, even if we reduce the bit depth.

    The dithering duel: POWR 1 (standard) vs. POWR 3 (noise shaping)

    There are different methods of dithering. At Mother Earth Radio, we had the choice between POWR 1 (a standard dithering without pronounced noise shaping) and POWR 3 (with noise shaping).

    Conventional theory often states that noise shaping (as in POWR 3) is advantageous. Why? It shifts the energy of the dithering noise from the frequency ranges where our hearing is most sensitive (the mids) to the higher, less sensitive frequencies. The overall noise level tends to be even higher – but it is concentrated where we should perceive it least. For classical music in particular, with its extremely quiet passages, this has often been advertised as the superior method for keeping the finest details in the mid-range free of noise.

    The practical shock: John Mayer and the acoustic guitar

    Naturally, we wanted to put this theory to the test ourselves. Our initial tests with dense, complex pieces (such as the John Mayer Trio) showed little audible difference between the dithering methods. The music was so “full” that it effectively masked the dithering noise.

    John Mayer acoustic set

    But then came the litmus test: a solo acoustic recording of John Mayer – just his voice and a guitar. Here, with this transparent, intimate material, a clear difference suddenly became apparent , in favor of the standard dithering (POWR 1)!

    What we heard was an undesirable “sharpness” in the high guitar registers and with concise vocals when noise shaping (POWR 3) was applied. The original sounded much closer to the master WAV file with POWR 1. The theory that noise can be “hidden” in the high frequencies reached its limits here.

    Why our ear sometimes beats theory: The hi-res factor

    This observation raises important questions and confirms our skepticism about sweeping statements in the audio world:

    1. Human hearing is more complex: the assumption that “nothing is heard” above 20 kHz or that “you can do whatever you want with it” is too simplistic. Even if we do not perceive frequencies above 20 kHz as pitch, they can subtly influence the timbre, the sense of space, the precision of transients and the overall “naturalness” of the sound image. A concentration of noise in these regions may well manifest itself as an unpleasant harshness or sharpness in the perceived spectrum.
    2. Noise shaping and hi-res audio: Many noise shaping algorithms were developed and optimized in an era when 44.1 kHz and 48 kHz were the norm. At our extremely high sample rates of 192 kHz (and above in processing), where a much wider frequency range beyond 20 kHz exists, the effects of shifted noise can have a different, and possibly negative, impact. It seems that the algorithms in these regions sometimes produce artifacts that our “whole person” does perceive.

    The Mother Earth Radio Dithering conclusion

    Based on our extensive listening tests and in-depth research, we have opted for standard dithering (without aggressive noise shaping) at Mother Earth Radio. It may not theoretically offer “that last bit of midrange noise immunity”, but it delivers a more consistent, natural and, above all, unobtrusive sonic result for the full range of our vinyl material – from dense rock recordings to delicate acoustic music.

    It shows once again: while theory gives us a valuable guideline, in the end it is the trained ear of the sound engineer that makes the final decision. At Mother Earth Radio, we trust our ears to bring the “aura of music” to you as authentically as possible.

  • Mother Earth Radio: Vinyl recording workflow 64 bit float explained

    Nerd-torial: The Mother Earth Radio Vinyl Recording Workflow – Why we do (almost) everything right

    Welcome, dear audio nerds and sound aesthetes! At Mother Earth Radio, we value sound quality that breathes the spirit of music and touches the soul. But to achieve this, it takes more than just good records and a record player. It takes a sophisticated, technical workflow that gets the most out of every vinyl groove.

    In this nerd-torial, we take you on a deep dive into our vinyl recording and editing process. We explain why we made certain decisions and why our current workflow is very close to the ideal – even if we can’t do everything “perfectly”.

    Step 1: The supreme discipline – vinyl recording with the RME ADI-2 Pro FS

    It all starts with the analog source: our beloved records. At the heart of this step is the RME ADI-2 Pro FS. This high-end AD/DA converter is known for its precise and transparent conversion.

    Vinyl recording with the RME

    We record in 768 kHz and 32-bit integer. “Wait a minute”, one or two nerds may now interject, “why not 32-bit floating point?” That’s a perfectly valid question! The RME ADI-2 Pro FS converts internally with 32-bit integer. This means that it offers a fixed dynamic range of a gigantic 190 dB. This is far more than even the most dynamic record can ever deliver and also far beyond what our ears can perceive.

    The point is: when recording vinyl, where we can control the analog level via the preamplifier, the risk of digital clipping is virtually eliminated with the ADI-2 Pro FS – provided that we level out cleanly. We use the extremely high resolution of the converter to precisely capture every detail of the vinyl. The discussion about 32-bit float in recording is often more relevant in uncontrollable live environments where unexpected level peaks can occur. For our carefully controlled vinyl process, 32-bit integer is absolutely tops at this point.

    Step 2: The magic of post-processing – Sound Forge Pro 15 and 64 Bit Float

    Vinyl recording with Sound Forge Pro

    After recording in 768 kHz and 32-bit integer, the raw file ends up in our digital processing lab: Magix Sound Forge Pro 15. And here comes the real highlight that makes our workflow so powerful!

    As soon as the file is loaded into Sound Forge, it is converted into the 64-bit floating point format for internal processing. And this is where the aforementioned advantage of floating point comes into its own!

    What does 64-bit float mean? Imagine your audio data is no longer on a fixed ladder (as with Integer), but on a ladder that dynamically adjusts its rung spacing. The internal 64-bit float processing offers a virtually infinite dynamic range. This is where the “non-clipping” takes place. No matter how loud or quiet a signal gets internally, or how many calculations are performed – there is no more digital clipping.

    This is crucial for our processing steps:

    • DC Offset Removal: The removal of unwanted DC components in the signal.
    • Declicking: The sensitive removal of crackling and pops, which can unfortunately be part of the vinyl experience.
    • Resampling (multiple times): We go through several resampling processes from 768 kHz up to 192 kHz. Each of these steps requires complex recalculations of the audio data.
    • Pitch shifting: Another operation that requires immense computing power and precision.

    All these operations take place in the 64-bit float environment. The result: minimal rounding errors, maximum precision and absolutely no digital clipping during the entire processing chain. The integrity of the audio signal is preserved to the maximum.

    Step 3: Finishing – volume according to EBU R128 and dithering

    Once all the processing steps in the high-precision 64-bit float domain have been completed, it is time for the final refinement and export.

    1. Volume normalization to EBU R128 (-23 dBFS): We adjust the overall volume of the audio to the EBU R128 standard, more precisely to -23 LUFS (Loudness Units Full Scale). This standard is crucial for consistent playback across different platforms and ensures a pleasant listening experience. Thanks to floating point processing, we can make this adjustment precisely without losing information or clipping, even if the original level was significantly higher.
    2. POWR dithering to 24 bit: The last step before export is dithering. Here we reduce the internal 64-bit float precision to our target format of 24-bit integer. Now the layman might ask: “Won’t everything you did before with float be ‘perdu’ again?” The clear answer: No, absolutely not!Imagine you have created a perfect work of art in a huge studio (64-bit float). All colors, brushstrokes and details have been applied with the utmost care and precision. At the end, this masterpiece is placed in a perfectly fitting, high-quality frame (24-bit). The quality of the previous work is retained and is visible in the final result. Dithering is a mathematical process that deliberately adds a low, barely audible noise to mask quantization errors when scaling down the bit depth, thus ensuring the best possible quality in the reduced format. The POWR (Psychoacoustically Optimized Wordlength Reduction) dithering that we use is particularly optimized for human hearing.
    3. Encoding as FLAC: Finally, the file is encoded as FLAC (Free Lossless Audio Codec). FLAC is a lossless compression format. This means that the audio quality we have carefully worked out up to this point is fully preserved, while the file size is reduced.

    Why is this workflow “ultimate” (or at least damn close to it)?

    Mother Earth Radio’s workflow is a combination of high-quality hardware and intelligent software processing.

    • High-resolution recording: The RME ADI-2 Pro FS delivers an extremely precise digital image of the vinyl source.
    • Error-free internal processing: Sound Forge Pro 15’s 64-bit floating point engine virtually eliminates all digital clipping risks and ensures maximum precision in all processing steps. This is the decisive advantage that goes beyond the pure bit depth of the source file.
    • Quality preservation: Careful dithering practice ensures that the high quality of the internal processing is optimally transferred to the final 24-bit format.
    • Lossless distribution: FLAC guarantees that the listener gets exactly the quality we created in the studio.

    Although we don’t record directly in 32-bit float (which isn’t necessary in our vinyl digitization setup), we take advantage of floating point arithmetic where it matters most: throughout the entire processing chain. This makes our process one of the most advanced and quality-oriented workflows for record archiving and distribution.

    We hope this nerd-torial has given you a deeper insight into how we work. Stay tuned for more technical insights and of course great music on Mother Earth Radio!
