New sample rate
Upload an AAC file and resample it to the sample rate you need.
Broadcast chains and stream captures produce AAC at whatever rate the source used. This tool decodes, resamples, and re-encodes the stream at your chosen rate, keeping the ADTS framing pipelines expect.
Like all lossy round trips it costs a sliver of quality, so conform once and keep the result.
Many ingest points pin an exact sample rate (often 44.1 or 48 kHz) and refuse anything else. Resampling here usually resolves the rejection.
If you only need a container change, AAC to M4A is lossless and enough. Resample only when the rate itself must change.
