Select decoded audio by seconds, add optional nonoverlapping linear fades and export PCM16 WAV.

Outputs are cleared when the input changes.
Result
Enter your data or use the example, then run the tool.
Worked example
The generated 2.5-second stereo sample trimmed from 1 to 2 seconds gives exactly one second, with frames per channel equal to the reported decoded sample rate. Pure 48 kHz PCM gives 48000 frames.
Method
Decode locally into PCM, select each channel from floor(start × rate) to floor(end × rate), then apply optional linear fades from zero/to zero. Preserve decoded rate/channel count and encode interleaved signed little-endian PCM16 WAV. Report hard clipping if samples exceed -1 to 1.
Limits
One file up to 50 MiB; decoded mono/stereo up to five minutes and 28.8 million samples across channels. Only browser-decodable formats. Decoding may resample; output PCM16 WAV is quantized, not a lossless copy of the compressed stream. Native decode cannot be forcibly interrupted; cancellation ends the wait and cleans resources when possible.
Your inputs stay on this device. Only optional, consented page visits are measured. Input values, files, filenames and processing logs are not sent to Analytics.
When switching languages, text, settings and selected files are temporarily kept on this device. Transfers are removed after restoring; interrupted transfers are cleaned up on a later visit. Inputs and files are never uploaded.
