When macOS asks, allow the microphone and other recording permissions required by the selected source.
How to Record System Audio and Microphone on Mac
Capture Mac system sound, microphone input, or both together, then manage long sessions with auto stop, automatic splitting, and organized MP3, M4A, or WAV output.
Before You Start Recording
Confirm permissions, input, format, and storage before a long session so the saved recording contains the sound you expected.
Decide whether the task needs Mac system audio, microphone input, or both together.
Use MP3 or M4A for practical sharing and smaller files, or WAV when uncompressed output is preferred.
Choose a clear output folder and confirm that enough free space is available for the expected duration.
Choose Mac System Audio, Microphone, or Both
Select the input that matches the recording job before pressing Record.
- Open the audio input selection panel.
- Choose Mac system audio for browsers, media players, meetings, online music, and app sound.
- Choose the microphone for narration, interviews, lectures, or voice notes.
- Select both sources for lessons, demonstrations, commentary, and calls that need computer sound plus voice.
- Speak and play a short sample to confirm that the expected source is active.

Auto stop and automatic splitting reduce manual work during radio programs, livestreams, interviews, lessons, and other long captures.

Set Auto Stop
Choose the ending condition so a planned recording can finish without waiting for a manual Stop command.

Split by Time or File Size
Divide long sessions automatically by duration or file size so lectures, streams, and interviews remain easier to store and manage.

Audio Recorder for Mac FAQ
Why is Mac system audio missing?
Confirm that system audio is selected, required macOS permissions are allowed, and the application producing sound is playing through the active Mac output device.
Why is the microphone silent?
Select the correct built-in, USB, or external microphone and allow microphone access in macOS privacy settings.
How can I reduce echo?
Use headphones when recording system sound and microphone together, and prevent the microphone from capturing speaker playback.
How do I avoid one very large file?
Enable automatic splitting by duration or file size before starting the long recording.
Which output format should I choose?
MP3 is practical for broad sharing, M4A suits many Apple workflows, and WAV is useful when uncompressed audio is preferred.
Where are recordings saved?
Check the destination selected in the task or settings, then use the recorded file list to open the saved result.
