I would like to find out one of the best approaches on how to sample a certain sound in a song? Open-source/freeware software would be ideal but propriety software is welcomed as well. I'm looking to use these samples in live DJ performances and not music production. Thank you
If you are wanting to separate out a single sound from within a performance, you will need to use filters to try and remove frequencies higher and lower than those in the piece you want, but you will still be left with some noises.
If you can find the sound you want in a part of the song with no other instruments playing, this will be your best bet. Them just record it into your sampler.
