Transcription Resources. Software to slow down music.

There are various other tools aimed at helping people to transcribe music from recordings. Here are the ones I am currently aware of. None of them are in head-on competition with Transcribe! as they all have differing approaches. Personally I don't think any of them equal Transcribe! as a general purpose transcribing assistant but perhaps I'm biased - try them and see.

There are also tools which are quite different from Transcribe! such as hardware playback devices, and software which attempts automatic transcription (output as MIDI or notation, Transcribe! doesn't do).

Source Code

If you are a programmer and you want to know how to write such programs, some of the above projects are "open source" which means you can download the source code and look at it. For spectrum analysis see Music Explorer, and for slowdown see Best Practice. I haven't actually looked at the source for either of these so I can't say for sure what you'll find.

Using AI techniques to separate instruments from a mixed track

There are some very impressive projects in this area. Some of them are open source with unrestrictive licenses. However I don't have any immediate plan to incorporate anything like this into Transcribe!, mainly because they require a lot of code and more memory than the average user would have (16 GB is good). This is why these AI systems run on servers in the cloud, not on your machine. However you can use them yourself if you want to, and then load the result into Transcribe! Note that Transcribe! can load "stem" files, that is mp4 or ogg/mogg files with multiple soundtracks. Please see the FAQ "How can I work with "stem" files?"
