Trim a Long Recording without Losing the Full Timeline

A compressed MP3 expands substantially when decoded into floating-point audio. A two-hour stereo recording at 44.1 kHz needs roughly 2.5 GB for its raw samples alone, before effects, copies and export buffers.

Streaming playback reads the recording as needed instead of decoding the whole source into an in-memory waveform. The timeline uses the original media duration so you can reach the beginning, middle and ending.

Audixo noteMake one change, listen, then decide. Clear A/B decisions beat stacking effects blindly.

Drag the side handles to choose the source range, or enter exact seconds. To remove an unwanted middle section, mark its start and end and join the remaining parts. Listen around each boundary to check the transition.

For standard MP3 and PCM WAV, select Original quality and export the retained audio locally without decoding the entire recording. MP3 boundaries align to frames, so timing is approximate by a few milliseconds and joins can contain a small artifact. If you want new bitrate, fades, volume or speed, retain ten minutes or less for local re-encoding. Unsupported long formats need conversion before importing.
