Beat-making lives in samples. You pull audio from anywhere. YouTube rips, vinyl scans, AI generations. And chop, pitch, reverse, and stretch it into something new. The faster the in-browser pre-processing (clean up the source, get it into WAV, shift the pitch by a few semitones), the more time you spend writing.

WAV at the original sample rate of the source. Don't convert to MP3 first. It adds a generation of compression that survives chopping. Keep it lossless until the final beat is bounced.
Yes. That's exactly what a pitch shifter does. Shift up or down in semitones (or cents for fine tuning), and the time stays the same. For dramatic pitch shifts beyond ±5 semitones, expect some artifacts.
