MP3 Editing Tools
What Each MP3 Tool Does
MP3 Cutter / Trim — Trim MP3 lets you keep just the section you need. Enter a start and end point in seconds or mm:ss and export a clean clip. This is the fastest way to make a ringtone, grab a chorus, or remove silence from the start or end of a recording.
Merge MP3 — Merge MP3 joins several files into one continuous track. Combine podcast segments, audiobook chapters, or a set of songs into a single seamless file, arranged in the order you choose.
Normalize Volume — Normalize MP3 raises or lowers the overall loudness so every track sits at a consistent level. Essential when you have assembled audio from different sources that were recorded at different volumes.
Change Bitrate — The bitrate changer re-encodes your MP3 at a specific kbps. Lower the bitrate to save space, or set 320 kbps for maximum quality. See also MP3 to 320kbps and MP3 to 128kbps.
Speed Changer — Change the playback speed from 0.5× to 2×. Speed up podcasts and lectures, or slow down music and speech for practice and transcription.
Stereo to Mono — Downmix a two-channel track to a single mono channel. This roughly halves the file size and is ideal for voice recordings, phone systems, and mono playback devices.
Compress MP3 — Compress MP3 shrinks a file to a target size by adjusting the bitrate, so you can hit an email attachment or upload limit without changing the format.
