Release 3.1.0-beta.6

· One min read

3.1.0-beta.6 - 8 December 2024​

Updates:​

  • Fixed "Traktor Utilities" issue when loading collection showed no tracks (caused by Beatport tracks)
  • Fixed issue adding hidden files to the Queue. Happened when users selected folder to process & it contained hidden metadata files that don't contain any musical information (e.g. ".track.mp3"). Now all hidden files (starting with "." are omitted when adding to the Queue)

Release 3.1.0-alpha.33+32

· One min read

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%")

Release 3.1.0-alpha.31

· One min read

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

Release 3.1.0-alpha.28

· One min read

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)
