When you cut a WAV or FLAC file, the cutter can simply copy the relevant PCM samples — no encoding or decoding required. The output is bit-perfect. For lossy formats like MP3 or AAC, true "lossless cutting" is complicated by the fact that audio is stored in compressed frames. A cut in the middle of a frame requires either decoding and re-encoding (introducing quality loss) or accepting a slight imprecision at the cut boundary. FFmpeg's stream copy mode cuts at the nearest frame boundary, which typically means a difference of a few milliseconds — imperceptible in practice for most content.

How to Cut Audio Files Precisely: A Practical Guide
Cutting audio files sounds simple, but the details matter. The difference between a clean cut and an artefact-riddled one often comes down to understanding how your audio cutter handles codec frames, re-encoding, and timing precision. This guide explains everything you need to know to get perfect results every time.
Stream Copy vs Re-Encoding: Why It Matters
Entering Precise Start Times
The time format for audio cutting is flexible. All of the following are valid inputs: 1:30 (1 minute 30 seconds), 90 (90 seconds), 01:30:00 (1 hour 30 minutes), 1:30.500 (1 minute 30.5 seconds). For ringtone creation, aim for a start time that catches the song at a musically strong moment — an intro riff, a chorus, or a recognisable hook — rather than the very beginning of the track.
Creating iPhone Ringtones with the Audio Cutter
iPhone ringtones must be 30 seconds or shorter. The workflow: (1) cut your desired clip with the Audio Cutter; (2) convert the result to M4A (AAC) using the M4A Converter; (3) download the M4A file and rename the extension to .m4r; (4) open iTunes or Music on a Mac, drag the .m4r file in, and sync your iPhone. The custom ringtone then appears in Settings → Sounds & Haptics → Ringtone.
Extracting Audio Clips from Video Files
Uploading a video file (MP4, MKV, MOV, AVI) allows you to extract a specific time range of audio. This is useful for pulling dialogue from a film scene, extracting a song from a music video, or grabbing a sound effect from a long video recording. The audio cutter decodes the audio stream, cuts the specified range, and returns it as an audio file — all in one step, saving the intermediate step of a full audio extraction followed by a separate cut.
Best Practices for Podcast Editing with the Audio Cutter
For podcast segment extraction, identify your in and out points by listening to the recording and noting timestamps. When cutting, add 0.5–1 second of buffer before and after the desired segment to avoid cutting into words at the edges. If you need to remove noise at the beginning or end of the clip, run the result through the Noise Remover after cutting. For final delivery, re-encode the cut segment to 128 kbps MP3 mono using the Audio Compressor.
