|
| in a semi blind comparison, I prefer demucs for all 4 tracks

| most so let me say a couple words about them.
|
| bass - the demucs bass has less bleed from other instruments
| and the volume is consistent throughout. with spleeter, the
| volume varies a lot and there are multiple sections of 1-2 bars
| where it just drops out completely. In Capo, the demucs
| spectrogram is nice and clear whereas spleeter tends to look
| like pencil smudges for the most part.
|
| other - with spleeter, whenever there are vocals, the other
| instruments turn to mush. demucs is much better. Oh, you can
| tell people are singing -- the instruments get muffled -- but
| you can still hear them.

| repo instructions and then created a zsh alias to run it with any
| file name. Eg $ai_split mySong.mp3
|
| Wait fifteen minutes and out pops four stems, flawless so far,
| even been messing around with mainstream tracks and using ableton
| with warp applied to quickly build out remixes. Demucs is going
| to be /is already a game changer!

|
| Trying it out with Alan Walker's Alone, it separates the vocals
| and drums almost perfectly. Bass is really fine as well, only
| instrumental and 'other' was a bit mixed up in my try.
