{"listing":{"listing_type":"product","name":"Pitch Tempo","slug":"pitch-tempo","tagline":"Find song key and BPM; adjust recordings for practice","description":"Pitch Tempo is a free browser audio utility for singers, instrumentalists, dancers and creators. It estimates musical key and BPM, changes pitch from -12 to +12 semitones and tempo from 50% to 150% independently, and provides previews and downloadable exports. Files are processed on the server and can be up to 5 minutes and 100 MB. Guests need no account and can start 3 uploads per 24 hours; free accounts allow 5 per hour. Audio availability expires from the original upload: 24 hours for guests or 7 days for accounts. Each full export completes that chat.
