MP3 for broad compatibility
MP3 works with almost every player, editor and library. It is a practical choice when files will be used on different devices or systems.
Record MP3 and M4A
Choose the audio format that fits your workflow.
CAT exports completed recordings as MP3 or M4A/AAC. You can configure a separate bitrate for each format.
M4A/AAC for Apple workflows
M4A with AAC fits well into Mac and Apple workflows and produces compact audio files. CAT keeps the M4A and MP3 settings separate.
Set the bitrate for each format
The selected bitrate is applied during export, so you do not need an additional conversion step after every recording.
In practice
Record, organize and deliver in one Mac app.
CAT combines a focused audio source with exports you can use directly in your own workflow.
