r8brain PRO is a professional sample rate converter tool software designed to deliver an unprecedented sample rate conversion (SRC) quality. Unlike other existing SRC algorithms available on the market, r8brain PRO implements sample rate conversion processing in its full potential: interpolation and decimation steps without exploiting any kind of simplifications; the signal is resampled in a multi-step manner using a series of intermediate sample rates based on whole-numbered up/down factors. This makes conversion perfect – both in signal-to-noise and timing precision aspects. Such whole number-factored SRC can be considered a golden standard in sample rate conversion since it is not subject to jitter nor timing errors.

Like many existing SRC algorithms, r8brain PRO offers you a linear-phase conversion mode. But more importantly, you also have an option of using the minimum-phase conversion mode, which finally brings SRC with true analog qualities to affordable digital audio workstations: in this mode, r8brain PRO works like an ideal digital-to-analog converter followed by an analog-to-digital converter, to resample the audio. This eliminates pre-ringing associated with linear-phase designs while introducing a minimal amount of phase coloration.

r8brain PRO can read mono, stereo, and multi-channel files in WAV, RF64, Wave64, and AIFF file formats, creating 16-, 24-, 32-, and 64-bit mono, stereo, and multi-channel WAV (RF64) files in fixed- and floating-point formats. EBU BWF (broadcasting) extensions, extensible wave format, markers, sample loops, and textual data residing inside a file are also supported. For the sake of convenience, r8brain PRO allows you to perform multi-threaded batch conversions that utilize the full potential of your computer.

r8brain PRO's bit-depth conversion uses an industry-standard “flat” TPDF dithering. We have decided not to implement noise-shaping dithering because audio production software available on the market usually offers the user a noise-shaping dithering of some kind already (you can also use our Elephant plug-in for this feature). We also based our decision on the fact that the sample rate conversion process often adjusts peak profile of the original program material, thus, in many cases, making a subsequent peak-limiting a necessity. To prevent output audio from clipping we have implemented a level normalization feature.

TCD says:
Just install and enjoy! Team V.R appears in this release to say hello to everybody. It wasn't a far journey for V.R to find the way to Voxengo to appear! heh, Friend Gordon Shumway was not available at the time of compilation, unfortunately.

If anyone wonders why the previous version is 2.5, the previous version is actually 2.05 and the notataion comes from a coding standard of numbering the releases

Maybe you had a version from a long time ago. The previous version was v2.9, included in V.R last Voxengo bundle from April 2, 2022. Not a one of you could imagine the insane amount of work that went into making just that, of all V.R does, unless you do similar yourself. Serious. :)

Your work is kindly appreciated! Also for the nice technical explanations for those who like to nerd it out

indeed, I had an old version. anyway, the purpose of my message was nowhere near trying to downplay the work that has been done, just to clear out potential versioning confusion. we (the non-coders) tend to add a zero at the end (so will read 2.9 as 2.90) and when we compare with 2.10 it may get confusing

nice to have the best Dithering service,! but .. how to use it? .. render the master version in 32bit 48000hrz and then open it in r8brain PRO and render it in 16bit 44.100? .. who knows how is the best use for it?

If manually, first SRC, then dither. Dither is always last before bit reduction option setting.
So:
1. 48000 32 bit -> 44100 32 bit (no dither)
2. 44100 32 bit -> 44100 16 bit (dither)

Dither only:
- when go from higher bit depth to lower (from 32/64 to 24 or 16, or from 24 to 16)
- from float to int/fixed bit depth (32 or 64 to 24 or 16)
- 24 bit dithering realtime - anytime when monitoring, because when all your 32/64 float audio hits your 24bit DAC on output, it truncates. Sonically no difference, because you have huge range, but it is still safer!

No dither for saving audio in 32/64 bit, both either fixed/int or float.

Why 24 bit dithering? Because: it is still safer when no dithering when you go from your 32/64 bit... While mastering from DAC to analog too, you get 24 bit dithered output
