Why ChatCut
Choose the start and end in seconds. Everything outside that range is left out of the result.
Enter values such as 2.50 and 12.75 to define a short excerpt.
Listen to the original recording beside the time controls to locate the section you need.
WAV sources default to WAV; other inputs default to MP3. You can change the format before cutting.
The recording stays in your browser during processing. No account or upload is needed.
Play the trimmed result, check its time range and file size, then download.
How it works
Select an audio file up to 10 minutes long and 200 MB.
Enter start and end in seconds. Leave End blank to keep everything after the start, then choose MP3 or WAV.
Run the cut, listen to the excerpt and save the audio.
Learn
This audio cutter keeps the section between the start and end times and leaves everything else out of the downloaded file. Enter times in seconds, including decimals when needed. For example, start at 12.50 and end at 27.50 to select a fifteen-second passage. Leave End blank to keep the rest of the recording after your start point. The source preview helps you locate the passage, but this is not a multi-section timeline for removing several pauses in one pass.
A cut in the middle of a word can make a spoken excerpt difficult to follow. Start just before the first sound you need and leave enough room for the final syllable or musical decay. Preview the result to check these boundaries. The local tool does not apply a fade, a crossfade, or noise reduction, so silence or background sound inside the chosen range remains. If you want several separate excerpts, keep the source and make each selection from that original.
The tool re-encodes the selected range at 48 kHz stereo. MP3 output uses 192 kbps; WAV uses uncompressed 16-bit PCM. A WAV source initially selects WAV, while other inputs initially select MP3, and you can change that choice before trimming. Compressed source audio is not restored by saving it as WAV. Choose according to the next task: a listening copy may suit MP3, while another audio edit may call for WAV to avoid an additional lossy output encode.
The input limit is ten minutes and 200 MB, even when the excerpt you want is much shorter. The browser must be able to decode the source before it can produce that excerpt. Start must be zero or later, End must follow Start, and the chosen range must fit within the recording. If a long source exceeds the limit, prepare a shorter source in an editor first. The downloaded cut is separate, so keep the original when trying different boundaries.
