Description

The first time you use this tool, you need to wait for FFmpeg.wasm to download and load.

This tool is built on FFmpeg.wasm, porting the industry-standard FFmpeg multimedia processing engine to the browser via WebAssembly technology. All audio processing operations are completed on your local device without uploading to any server, ensuring the privacy and security of your audio files.

The format for start and end times is: HH:mm:ss.SSS (hours:minutes:seconds.milliseconds), for example: 00:05:30.123, which means 5 minutes 30 seconds 123 milliseconds.

Audio Bitrate: The amount of audio data processed or transmitted per unit of time (per second), usually measured in kbps (kilobits per second). It is the core parameter affecting audio quality and file size.

Below is a detailed comparison of common audio bitrates and their applicable scenarios:
Bitrate Quality Level Format Examples Applicable Scenarios
32-64 kbps Voice Grade MP3, AAC, Opus Voice calls, podcasts, audiobooks, voice memos
96-128 kbps Standard Quality MP3, AAC Streaming music (data saving), background music, standard headphone listening
192 kbps Good Quality MP3, AAC Daily music enjoyment, standard quality on online music platforms
256 kbps High Quality AAC (iTunes), MP3 High-quality options on mainstream music platforms, car audio systems
320 kbps Premium Quality MP3 (Maximum) Entry-level audiophiles, preliminary professional monitoring, local music collections
500-1411 kbps Lossless/CD Quality FLAC, ALAC, WAV, AIFF Professional audio production, music archiving, Hi-Fi audio systems
>1411 kbps High-Resolution DSD, 24bit/96kHz+ FLAC Mastering, top-tier audiophile equipment, professional recording studios
