trim WAV online
WAV stores audio in uncompressed PCM, each sample is an exact numeric value, with no lossy decoding along the way. That leaves trimming free to focus purely on precision: the minimum allowed selection is 0.02s (20ms), the typed time field accepts formats like 1:02.350, and every cut point gets adjusted before export.
The original sample rate survives the trim, the bit depth does not, because this tool's WAV encoder always writes 16 bits.
A comma is accepted as the decimal separator, so a pt-BR keyboard does not need to switch to a dot mid-typing.
The tool stretches the end point up to the 0.02s minimum instead of rejecting the selection, so drag-to-select keeps working even near the limit.
The Audio Trimmer accepts MP3, WAV, OGG/Vorbis, FLAC, AAC, M4A, and WebM. The exact support depends on the codec implemented by the browser, but the most common formats work in all modern browsers.
No. The trim always exports 16-bit PCM, even when the source file is 24-bit or 32-bit float. The original sample rate is preserved normally, only the bit depth is standardized to 16. To keep 24 bits intact, use this result as a reference and redo the cut in a DAW.
Because 0.02s is the internal floor used both for a trim selection and for each half of a split. Below that, the zero-crossing snap window (5ms) and the de-click ramp (8ms) applied at each edge would not have enough samples to work properly, and the result would sound worse, not better.
Yes. There is no re-encoding in the lossy-compression sense, WAV never goes through a lossy codec. What happens is a direct read of the selected segment's PCM samples, followed by a zero-crossing snap and an 8ms micro-ramp at the edges, then a new 16-bit WAV header written around that data.
