Frequently Asked Questions
What is audio normalisation?
Normalisation adjusts the overall volume of an audio file so that the loudest peak reaches a target level (typically 0 dBFS for peak normalisation, or a target LUFS for loudness normalisation). It makes audio consistently loud without clipping.
What is the difference between volume boost and normalisation?
Volume boost (gain) simply multiplies the audio signal by a fixed factor, making everything louder. Normalisation analyses the file and applies the exact gain needed to bring the loudest peak to a target level. Normalisation is smarter but requires analysing the whole file first.
Does changing audio speed affect the pitch?
Our Change Audio Speed tool uses time-stretching algorithms to change speed while preserving pitch, so speeding up a recording does not make voices sound like chipmunks. Some simpler tools do change pitch proportionally to speed, so check the tool description.
How does silence removal work?
The Remove Silence tool detects sections where the audio volume drops below a threshold for a configurable minimum duration, then removes those sections. This is useful for tightening up recordings, removing pauses between sentences, or cleaning up raw interview audio.
