How it works
Enter start and end times in seconds. The source is decoded locally at 48 kHz, then the selected PCM interval is exported. This is not a lossless MP3 frame editor.
Worked example
Start 12.5 and end 20 exports 7.5 seconds. The output is 24-bit PCM WAV; a lossy source does not regain lost detail. Keep your original file.
Read the result
Start and end define a time interval inside the decoded source. This tool exports the selected PCM frames as a new WAV, leaving the original untouched. Browser decoding is not a bit-exact MP3 frame cut, and the output can be larger than the source.
Common mistakes
Check that end is after start and within the source duration. Cutting at an abrupt waveform discontinuity can cause a click; this tool does not invent a fade or hide that edit. Audition the downloaded segment and retain the unedited file.
Questions musicians ask
How to trim audio files?
Choose a supported audio file, enter start and end in seconds, create the trimmed WAV and listen to it before downloading. Processing stays in the browser; the current local limit is 30 MiB and four minutes.
Can you trim an MP3 file?
Yes, by decoding it and exporting the selected interval as PCM WAV. MixGlint does not claim this is a lossless MP3 bitstream editor. The original lossy encoding's discarded detail remains discarded.
How to cut a WAV file?
Set the required time range and export it. For example, 12.5 to 20 seconds is a 7.5-second selection. The tool resamples on decode to 48 kHz and writes 24-bit PCM, so retain the original if exact source bytes matter.

From measurement to mastering
Understand the measurement, then compare your own mix and reference. Your ears remain the final judge.
