Frequently asked questions

Simple answers to your questions

What is audio compression?
Audio compression reduces the file size of a recording by changing how its audio data is stored. It can help make voice notes, podcasts, music and meeting recordings easier to share.
Will compressed audio still sound clear?
That depends on the compression level and the original recording. Voice-focused files often remain understandable at smaller sizes, while music and detailed sound recordings may need more data to preserve fidelity.
Why compress an audio file before sending it?
Large recordings can be difficult to attach to emails or upload to shared workspaces. Compressing the file can make it more practical to send, store and access.
Can I compress a voice memo?
Yes. Compressing a voice memo can help when you need to share a longer recording with a colleague, save it in a project folder or attach it to a form.
