Frequently Asked Questions
What does an audio speed changer do?
An audio speed changer allows you to adjust the playback speed of audio files. You can slow down audio (less than 1x) for transcribing or learning, or speed it up (more than 1x) to consume content faster.
Does changing speed affect audio pitch?
This tool adjusts the audio speed without special pitch correction. When you slow down audio, the pitch may become lower. When you speed it up, the pitch may become higher. This is similar to playing a tape faster or slower.
What audio formats are supported?
We support conversion to WAV format from MP3, WAV, OGG, WebM, AAC, FLAC, and M4A. The output is provided in high-quality WAV format which can be easily converted to other formats if needed.
Is there a file size limit?
Yes, the maximum file size is 100MB per audio file. This ensures smooth processing in your browser without performance issues.
Is my audio data safe and private?
Absolutely. All audio processing happens locally in your browser. Your audio files are never uploaded to any server. Once you close or refresh the page, all data is automatically cleared.
