Questions about Stems files in Traktor Pro 4

2TB and you're worried about MP3 sizes??

You could get close to 30,000 70mb stem files or loss files on a 2TB drive, you don't need anywhere near that in an entire music collection let alone in Traktor! You could fit over 200,000 320kbps MP3s!!

I've only got 1TB and I've never once thought or cared about disk space, and everything i've got is in Apple Lossless and i've been making my old Apple Lossless STEM files which are 120mb each.

• - Comparison for a 7 min track

FLAC file extention.flac 50mb bitrate 1441 kb/s
STEM file AAC extention.m4a 75mb bitrate 256 kb/s
STEM file ALAC extention.m4a 160 mb bitrate 1441 kb/s

for those having concerns with disk space it is cheap and fast in 2024 , if you have a mac or pc you can put it an external nvme drive too in a usb port as long as it has the new usb standards usb 3.1 gen2 or above.
if you have a laptop or pc upgrade internals with nvme drives , file transfer is lightning fast.

INTERNAL DRIVE M.2

PCI Express 4.0 NVMe pro tier: 7,450/6,900 MB/s (read/write) 180EUR for 2TB
PCI Express 3.0 NVMe pro tier: 3,500/2,700 MB/s (read/write)
PCI Express 3.0 NVMe low tier: up to 560 MB/s (read/write)

if you are into music then less than 200 EUR for storage is cheap !

EXTERNAL USB

• TB 3 and USB 4: These ports can achieve data transfer speeds of up to 40 Gbps, which translates to a maximum of 5,000 MB/s.
• USB 3.1 Gen 2: Ports supporting this standard can reach speeds of up to 10 Gbps, equating to a maximum of 1,250 MB/s.
• USB 3.1 Gen 1: This standard offers speeds up to 5 Gbps, which is about 625 MB/s.
• USB 2.0: The slowest option, offering speeds up to 480 Mbps, translates to a maximum of 60 MB/s.

In 2024, it's best to consider devices/drives equipped with transfer speeds of 1 gigabit (1000 MB/s) or higher.


- COLLECTION COMPARISON

1000 LOSSY 256 kb/s STEM files take up 60 GB of drive space.
1000 LOSSLESS STEM files would take only up to 128GB of drive space ( not a lot in 2024 )

Standard audio quality pales in comparison once you've experienced the superior sound.
Once you experience the superior quality of mixing, there's no turning back. Even by using budget friendly high-quality flat-profile in-ear monitoring headphones, you'll be able to perceive all the frequencies and master every fine detail. The rush of dopamine coursing through your body, driven by the exceptional audio quality, will keep you engaged in that audio masterpiece that’s right at your fingertips.

ps: the most widely adopted open-source approach currently in use is htdemucs_4

Well he didn't actually say he bought them…

I don't like Izotope's separation, I prefer demucs via UVR5

I think that iZotope RX is using Demucs too. Maybe they don't use the same models, I'm not exactly sure.

But it's true that the OG Stem Creator support ALAC output if the input file is ALAC too. But ALAC stem files are not supported by Traktor on Windows… So it never was the default and they never made it easy. This is why I created Stemgen.

Generate a stem inside traktor, save collection, open collections.nml and take a look how the track looks in there. I would guess it's possible to write a program that does something similar.

@Didier Malenfant Maybe you can update TraktorBuddy to do that?

Something that lubes @axeldelafosse Stemgen with TraktorBuddy would be nice.
