Practice Player Guide
The Practice Player is an all-in-one tool for musicians who want to deeply study audio. Load any audio file and you can set loop points, slow down or speed up playback, and shift the pitch — all in real time inside your browser. No files are uploaded to a server. Processing happens entirely on your device.
A-B Loop
Press the A button to mark the start of a loop, then press B to mark the end. Once both are set, enable looping with the repeat button and playback will jump back to A every time it reaches B. This is ideal for drilling a difficult passage, transcribing solos, or memorizing a section. You can adjust the loop region at any time by pressing A or B again.
Speed Control
Use the speed slider to change playback from 0.25× to 2.0× while preserving pitch. SoundTouch processing can change texture or clarity, especially at extreme settings.
Pitch Shift
The Pitch slider shifts the key up or down by up to 12 semitones (one octave) in either direction, without changing the playback speed. Shift the pitch down to play along with a song in a lower key, or up to practice in a higher key. Use it to match a track to the tuning of your instrument when a capo or retuning is not practical.
Tips
Combine a short A-B loop with slow playback and gradually raise the speed. Speed control preserves pitch; adjust the pitch slider only when you want to practice in a different key.
How to use this tool and common questions
Loop a passage, slow audio down to 0.25× or speed it up to 2×, and shift pitch by ±12 semitones. Try the ToneNook practice player with a built-in demo.
- How can I slow down and repeat a passage?
- Choose an audio file or open the demo, then set points A and B around the passage. Enable looping and reduce playback speed to practice the difficult section.
- Can I change speed and pitch separately?
- Speed can be adjusted from 0.25× to 2× and pitch from -12 to +12 semitones independently. Extreme settings can affect the sound, so adjust them while listening.
