Transcription Resources. Software to slow down music.
Fake Book Index
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).
Software - desktop
AKoff Music Composer
It's also worth mentioning that Windows Media Player version 10 and Apple's QuickTime version 7 are both capable of slowing down music without changing pitch. In fact, the internet is awash with software to slow down music without changing the pitch. I'm glad Transcribe! does so much more than that.
Windows Media Player version 10 instructions : load the track for playing in Windows Media Player, select "View" at the top, and under "Enhancements", select "Show Enhancements". Then go to the "Now Playing" tab, and you can use the slider to slow the piece down.
QuickTime version 7 instructions : load the track into QuickTime Player, and on the Window menu select "Show A/V Controls". There is a "Playback Speed" slider in this window.
QuickTime version 10 (QuickTime X, released with OS 10.6 Snow Leopard) : does not seem to be capable of doing this. I have heard it said that future versions may be able to. In the meantime, you can install QuickTime 7 alongside Quicktime X if you want to. Search the web for "Quicktime 7 Snow Leopard" (without the quotes) for more info.
Software - iOS
Amazing Slow Downer
Software - Android
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.
