Version update 1.3 features a lot of new useful improvements and minor issue fixes. r8brain PRO now supports a variety of non-standard sample rates as well.

The most useful improvement of this version is the new "Ultra Steep" conversion mode which offers an excellent bandwidth (less than 1.5% high-frequency rejection) at the expense of conversion times.  This clearly eliminates all further questions about high-frequency roll-off and any possible aliasing artifacts: in the "Ultra Steep" mode both these problems finally go away.

We are also keeping an eye on advancements of our competitors.  That is why this version update offers a slightly improved sample rate conversion quality and overall increased SNR.

For your information, r8brain PRO implements sample rate conversion processing in its full: interpolation and decimation steps without exploiting any kind of simplifications; the signal is first resampled to a least common multiple sample rate which makes conversion perfect.

r8brain PRO features:

  • Reads 8-, 16-, 24-, 32-bit PCM and IEEE files
  • Reads both WAV and AIFF files
  • Writes 16-, 24-, 32-bit PCM and IEEE WAV files
  • Multi-channel file support
  • Extensible wave format support
  • EBU BWF extensions support
  • Linear- and minimum-phase modes
  • Ultra-steep conversion mode
  • Batch support
  • Automatic normalization
  • Supports all standard sample rates

These are definitely the type of words i like to hear. i will be downloading the new version immediately!


An important 'last moment fix' version 1.3.1 is available.  It fixes 'too slow' 44.1<>48 kHz sample rate conversion.  But more important, sample rate conversion to/from 44.1, 48, 88.2, 96 kHz is now faster than in all previous versions.  96k to 44.1k is TWO times faster according to my measurements.
