How to Record Internal Audio and Auto-Split It into Tracks
Do you want to record the audio playing on your Mac and turn it straight into separate tracks, without cutting a single file by hand? NeonWaves lets you record internal audio and split tracks automatically in the same session. Here’s exactly how to do it.

Before You Start: Route Your Mac’s Internal Audio
To record internal audio, your Mac’s sound first needs to be routed into NeonWaves using a virtual audio device such as BlackHole. This setup only takes a few minutes, and once it’s done, you won’t need to repeat it for future recordings.
We’ve covered this setup step by step in a separate guide: How to Record Internal Audio on a Mac.
Disclaimer: BlackHole is a third-party audio driver and is not created, maintained, or supported by NeonWaves. Please refer to BlackHole’s own official channels for installation support.
Step 1: Check Your Device Settings
Once your virtual audio device is set up, open NeonWaves and go to Options, then Settings, then Devices. Make sure either the Default option or your created aggregate device is selected.
Choose your microphone or audio input device to record audio on Mac with the input source you want
Step 2: Record Your Internal Audio
Now the easy part. Press Record, and when you’re finished, click the Record button again to stop. Your entire recording appears immediately as an editable waveform, ready for the next step.

Step 3: Split the Recording Automatically
Instead of cutting every track manually, let NeonWaves do it for you:
- Go to Edit, then Auto-Cue, and select Cue Audio Starts by Silence.
- NeonWaves detects the silent gaps between tracks and automatically creates cue points at each track boundary.
This works the same way whether you recorded a single long file from your microphone or, in this case, directly from your Mac’s internal audio.
Automatically find silence and split long audio recordings into separate tracks
Step 4: Review and Rename Your Tracks
Go to Options, then open the Cue List. Here, you can see every separated track NeonWaves detected, and rename them if you want cleaner file names before exporting.
Step 5: Export Your Split Tracks
Once everything looks right, click Save as Audio, choose your destination folder, and export.
That’s it! One long internal-audio recording becomes multiple individual WAV files, without you cutting or saving a single track by hand.

Why Record Internal Audio and Split Tracks Together?
Combining these two features saves real time when you’re capturing something like:
- An album or playlist you want as separate song files
- A long webinar or online course split into individual lessons
- A multi-part podcast or interview recorded straight from your Mac’s audio output
Instead of recording once and manually chopping the file up afterward, NeonWaves handles both the capture and the splitting in one continuous workflow!
