I am looking for audio samples with very distinct beats and with constant tempos, does anyone know where I can find them? The tempo of the audio samples should also be available.I am looking to use these samples to help develop a tempo detection and beat tracking application.
If you are going to be using them to create a tempo detection program and need something constant Audacity has a great tool for creating metronome tracks.
- If you haven't already download and install Audacity from http://audacity.sourceforge.net/
- Open Audacity
Navigate to the menu Generate > Click Track
Choose the tempo and other various setting you wish to set, the click track plug-in is fairly robust and it should do everything you are asking.
However this will be very ideal tracks and will not have the full spectrum of sound as you would have with an actual audio track.
Why would you want to look at constant tempo songs only? Would your tempo detection work for constant tempo songs only? What would it do with non-constant songs? Imho, one task of tempo detection would be to discriminate between constant and non-constant tempo songs. TempoPlayer app for iOS categorizes songs by BPM and lets the user set his preferred "constancy limit".
