How to use Podcast Preview Clip Maker

  1. Upload the full episode.
  2. Choose the preview start, length, and edge fade.
  3. Create the clip, preview it, and download the WAV.

What this audio tool does

The clip maker copies the selected section into a new buffer and applies equal-length linear fades at both edges.

Time values are converted to exact sample positions, copied channel by channel, and encoded as a new PCM WAV.

WAV output is broadly playable but larger than MP3 or AAC. The maximum preview length is 180 seconds.

Supported formats and limits

Input support follows the codecs available to your browser. WAV is used for generated PCM output, while recording tools use a supported WebM codec. Large or long files require more memory and processing time.

Example and practical tips

Create a 30-second excerpt around a strong quote and use a 0.35-second fade to soften both cuts.

  • Start a fraction of a second before the first word.
  • Avoid clipping a sentence midway through.
