What audio formats are supported for output?

You can export your finished podcast trailer in MP3, WAV, FLAC, M4A, or OGG formats.

How many highlight clips can I include in a single trailer?

You can upload a minimum of one and up to five highlight clips to be concatenated.

What does the 'Music Under Clips' setting do?

It controls the volume level (in decibels) of the background music bed while your highlight clips are playing, ducking it so the voices remain clear.

Can I adjust the duration of each highlight clip?

Yes, you can set the clip duration anywhere between 2 and 120 seconds, and the tool will trim them automatically.

What loudness targets can I set for the output?

You can set a target LUFS value between -30 and -5 to match the requirements of different distribution platforms.

Details

What this tool helps you do

Builds a promotional trailer in one pass: the intro music plays, then your highlight clips are concatenated (or crossfaded) with a background music bed ducked underneath, and the whole thing is loudness-normalized to a platform target (Spotify/Apple Podcasts/etc.). Each clip is trimmed to the duration you set. Optionally add a closing music outro. Great for 15-60 second social media teasers.
