If you need a short audio clip for a bug report or a demo, the waveform is a good place to find it. For a clip someone else needs to reproduce, write down the timestamps and check the exported file. A preview tells you how the cut sounds. The file itself tells you what you actually saved.

This walkthrough uses a two-second test tone from FlowPick. The goal is to keep the middle second, from 0.500 to 1.500, and export it as a mono WAV at 44100 Hz.

Set the cut in FlowPick

  1. Open the FlowPick Audio Trimmer and load the flowpick-tone.wav sample listed on the page. You can also choose a recording from your device.
  2. Enter 0:00.500 in Start time and 0:01.500 in End time. For speech, drag the waveform handles to find the rough boundaries first, then use the time fields to fine-tune them.
  3. Select Keep selection. The output duration should read one second. Remove selection cuts out the highlighted section and joins the audio on either side. With this particular sample, both modes leave one second of audio, so the duration alone won't tell you if you picked the right mode.
  4. Click Preview edit. If you're cutting speech, listen for a clipped consonant at the start or the end of a word that disappears. A small adjustment to either timestamp is usually easier than fixing the cut after export.
  5. Choose WAV as the output format and keep the original sample rate. Run the trim, then download the result.

The screenshot uses a different recording to show where the controls are. Use 0:00.500 and 0:01.500 for the test tone.

FlowPick processes the selected recording in your browser. Large files can take longer to decode and may run into device memory limits.

Check the exported file with ffprobe

If you have FFmpeg installed, run this against the downloaded file. Replace trimmed.wav with its actual name.

ffprobe -v error -select_streams a:0 -show_entries stream=sample_rate,channels,duration -of json "trimmed.wav"

For this example, expect sample_rate to be "44100", channels to be 1, and duration to be "1.000000". If you see two seconds, check that you opened the export instead of the source file. If the duration is right but the edit sounds wrong, play the downloaded WAV and check which edit mode you used. ffprobe can verify the file's properties, but it can't tell you whether the cut landed on the right word.
