3.1.0-beta.2 - 18 October 2024​

Includes everything from 3.1.0-alpha releases prior to this date:

3.1.0-alpha.33+32 - 11 September 2024​

Updates:​

• New AAC Encoder on Windows -- QAAC (instead of FFMPEG aac). On Windows, NUO-STEMS is now using QAAC as AAC encoder. In simple terms: 256 AAC compression of stems shall be significantly improved resulting in higher quality. QAAC provides results that are almost identical to Mac AAC encoding.
• NEW Feature: "AI distribute on 'drums' and 'other' stem" -- when using "sum of stems = original", new option is now selected by default.
  • It substantially cleans up "other" stem from leftovers of drums & percussion, while keeping "sum of stems = original"

Fixes:​

• fixed issue of not being able to convert using htdemucs & htdemucs_ft algorithms (resulting is "-1%")

3.1.0-alpha.31 - 4 September 2024​

Updates:​

• Fixed a bug where conversion got stuck on "-1 %" if lyrics of the track contained special symbols.

• 3.1.0-alpha.31 -- VERY IMPORTANT UPDATE.

  TLDR: You need to re-convert your STEMS if you used mel_band_roformer before.

  So, I discovered a bug that quality was not improved prior to this release, and it stayed the same as 3.0.0 for drums, bass & other.

  What it means (I'm comparing PRE-3.1.0-alpha.30 and 3.1.0-alpha.31):

  SDR (quality metric - check this video for explanation: (https://www.youtube.com/watch?v=NxphQmFIlk0&pp=ygUJbnVvIHN0ZW1z) ):

  • Drums: improved: 11.26 > 11.77
  • Bass: improved: 12.04 > 12.38 (you can actually hear that there are now very little drums leaks)
  • Other: improved: 5.74 > 6.90 (also, drums leaks are now minimal. Another bonus: of you enable "sum of stems = original", it now goes into "other" stem quite well)
  • Vocals: 10.85. (nothing changed here since release of mel_band_roformer)

  What it all means, is that quality improved substantially in different areas, and if you used "mel_band_roformer" algorithm to convert to STEMS since it's release, you now need to re-convert all your tracks to actually gain quality increases in all stems, and not just vocal

3.1.0-alpha.29 - 26 August 2024​

Updates:​

• fixed issue of "empty vocals" on MacOS 14+

3.1.0-alpha.28 - 25 August 2024​

Updates:​

• New "Sum of stems = original mix" feature. Makes sum of stems (drums, bass, other, vocals) exactly equal original mix. Keep in mind that this will make the stem that you selected very "dirty".
• New "Added silence duration feature". 100ms of additional silence was introduced in early versions of 3.1.0-alpha. Now there is an option to enable/disable adding 100ms of silence to the beginning of the track.
• Saving .wav stems now has additional option - "Template of the filename". You can now select whether you want to append/prepend original filename to each individual stem, or leave it without it. (example: filename_vocals.wav)

3.1.0-alpha.27 - 24 August 2024​

Updates:​

• fixed issue where users of old Mac OS systems (10.15) had progress stuck at 3%

3.1.0-alpha.26 - 23 August 2024​

Updates:​

• completely reworked under-the-hood to potentially provide more stable performance for "mel_band_roformer" & other algorithms. You might also experience higher benchmark on systems with good NVidia GPU or Apple Silicon
• added new preset for STEMS Colors - "Traktor Pro 4" color preset
• removed "STEMS Metadata" section from Settings
• removed "mdx_extra" algorithm, as mentioned in previous post (it's outdated & almost nobody uses it)

3.1.0-alpha.25 - 11 August 2024​

Convert & Settings:​

• BIG UPDATE: new algorithm "mel_band_roformer". Also known as "insane".

3.1.0-alpha.20 - 30 July 2024​

Convert:​

• Fixed issue when lyrics of input file contained special characters that caused program to freeze

3.1.0-alpha.18+19 - 29 July 2024​

Convert:​

• added .mp4 as supported extension for adding to the queue
• Fixed issue when mono files where added to the queue

Traktor Utilities & Settings:​

• "Load Traktor Collection" disable option. If disabled -- Traktor collection won't be loaded & Traktor Utilities will be disabled
