Common questions
When should I use Pitch Changer?
Use Pitch Changer when you already have a local audio file and want to move it to a new key. It is the right starting point for testing a friendlier key, comparing semitone moves, or exporting a changed version for rehearsal.
When should I use Audio Speed Changer?
Use Audio Speed Changer when you want to slow a local file down for rehearsal detail or speed it up for fluency checks while keeping the pitch steady. It is the right starting point when pacing is the question, not the key.
When should I use Metronome?
Use Metronome when the job is steady practice tempo rather than file processing. It is the right starting point when you need BPM control, bar accents, pulse shaping, and quick access to exact tempo or signature presets.
When should I use Tone Generator?
Use Tone Generator when you need a steady reference pitch instead of file processing or a repeating click. It is the right starting point for tuning, ear training, sound checks, and exact Hz playback.
Do these tools stay local to my device?
Yes. Pitch Changer and Audio Speed Changer process the file on your device, Metronome generates its click on your device, and Tone Generator sounds its reference tone there as well.
What are the extra starting points for?
They open each tool on a more specific setup, such as MP3 key changes, slowing a file down while keeping pitch steady, exact BPM targets, common signatures like 6/8, or tone presets for notes like A4 and fixed references like 432 Hz or 440 Hz.
