Choosing tools and common questions
How do tempo and pitch changes differ?
Tempo changes duration while approximately keeping pitch. Pitch shifting changes semitones with tempo compensation to approximately retain duration. Extreme processing can alter timbre.
What limits apply to audio input and output?
New editors accept up to 10 MB and 30 minutes; reverse and recording are limited to 5 minutes. Ringtone sources can be 30 minutes long, while the selected interval is limited to 40 seconds. MP3/WAV outputs total at most 150 MB, including all split pieces.
Does Recorder automatically open the microphone?
No. Only Start requests permission; Stop or leaving the tool closes microphone tracks. HTTPS is required. Native browser recordings can also be converted to MP3 or WAV.
Do these tools separate vocals or reduce noise?
These are basic editors without AI vocal separation, intelligent denoising or transcription. Silence removal uses level thresholds rather than sentence meaning; listen before saving.
Should I export songs or recordings as MP3 or WAV?
MP3 is usually smaller for sharing and everyday listening. WAV suits further editing but can be much larger than the compressed source. Converting to WAV does not recover lost detail; check output size for long recordings.
