▍What is sound-goods Cutter?

sound-goods Cutter is a free online audio editor that lets you trim any audio file to the exact segment you want — and export it as a high-quality MP3 — without uploading anything to a server. Everything runs inside your web browser using the Web Audio API and a JavaScript MP3 encoder called lamejs. Your file is processed on your own device and stays there.

Most competing tools — including well-known names like mp3cut.net, Clideo, and AudioTrimmer — send your audio to their servers to process it. That means waiting for an upload, waiting for processing, and your audio passing through infrastructure you don't control. sound-goods eliminates all of that. The result is a cutter that is faster, more private, and works on files of any size.

How it works technically: When you drop a file into the editor, your browser decodes it into raw audio samples using the Web Audio API. You select your region using the waveform handles, apply optional fades, and click Export. The selected samples are fed into lamejs — an open-source MP3 encoder that runs entirely in JavaScript — which encodes them to a 192kbps MP3 file and triggers a download. No network request is made at any point.

▍How to cut an MP3 — step by step

Load your audio file
Drag and drop your MP3, WAV, OGG, FLAC, or M4A file onto the editor above — or click to browse. The file is decoded immediately in your browser. No upload happens.
Select your region on the waveform
The waveform shows the full amplitude of your audio track. Drag the left handle to set the start point and the right handle to set the end point. Use the Zoom slider to get frame-accurate precision on any section.
Preview your selection
Click Play to hear exactly the region you have selected, with a moving playhead on the waveform. Adjust the handles until the cut sounds exactly right before exporting.
Add fade in or fade out (optional)
Use the Fade in slider to ramp the volume up from silence at the start, and the Fade out slider to fade to silence at the end. Both can be set from 0 to 10 seconds. The waveform highlights each fade zone in green and red as you adjust.
Export your MP3
Click Export MP3. The encoder processes your selection in seconds and your browser downloads the trimmed file at 192kbps. Done — no waiting for a server.

▍Common use cases

Making a ringtone

Load your song, zoom into the chorus or the hook you want, drag the handles to a 20–30 second window, add a 1-second fade out, and export. The resulting MP3 is ready to set as a ringtone on Android. For iPhone, import the MP3 into iTunes and change the extension to .m4r to create a custom ringtone.

Trimming audio for social media

Instagram Reels accepts audio clips up to 90 seconds, TikTok up to 60 seconds, and YouTube Shorts up to 60 seconds. Load your track, select the best segment for your video, and export. The entire process takes under a minute without logging into any platform.

Editing a podcast or voice recording

Need to remove a long silence at the beginning of a recording, or isolate a single answer from an interview? Zoom in on the waveform to find the exact moment, set your handles precisely, and export the segment you need. Because no file is uploaded, this workflow is safe for confidential recordings, client calls, or unpublished content.

Cutting unreleased music

Producers and musicians who want to share a preview or clip without uploading to a third-party server can use sound-goods safely. Your unreleased track stays on your machine throughout the entire process.

Extracting a sample

Zoom up to 20× on the waveform to find the exact transient or phrase you want to sample. Use the playhead preview to confirm the selection sounds right before exporting.

▍Supported audio formats

sound-goods Cutter accepts the following input formats, all decoded natively by the Web Audio API in your browser:

  • MP3 — the most common compressed audio format. Supported by all browsers.
  • WAV — uncompressed PCM audio. Lossless quality but large file size.
  • OGG (Vorbis) — open-source compressed format. Supported in Chrome and Firefox.
  • FLAC — Free Lossless Audio Codec. Supported in Chrome, Firefox, and Edge.
  • M4A / AAC — Apple's compressed format. Widely supported across all modern browsers.

All exports are saved as 192kbps MP3, which offers near-transparent quality for music and is universally compatible with every device and platform.

Safari note: OGG and FLAC files may not decode on Safari due to Apple's codec restrictions. For maximum compatibility on macOS and iOS, use MP3, WAV, or M4A as your input format.

▍Privacy: why "no upload" matters

When you upload an audio file to an online tool, several things happen that you cannot control: the file travels across the internet unencrypted unless the site uses HTTPS, it sits on a foreign server for some period of time, it may be retained in logs, and it is subject to the data policies of that company. For most pop songs this is not a concern. For the following situations, it is:

  • Unreleased music or demos not yet publicly available
  • Confidential voice recordings, interviews, or meetings
  • Audio from private events or family recordings
  • Work produced under a non-disclosure agreement
  • Samples sourced from licensed material you do not have the right to share

sound-goods solves this by running the entire pipeline — decoding, editing, and encoding — inside your browser. The tool is technically incapable of sending your file anywhere because no network request for your audio is ever made.

▍Technical requirements

sound-goods Cutter requires a modern browser with Web Audio API support. All browsers released in 2020 or later meet this requirement:

  • Chrome 66 and above
  • Firefox 60 and above
  • Edge 79 and above
  • Safari 14 and above

No browser extension, plugin, Java applet, or Flash is required. The tool works on Windows, macOS, Linux, Android, and iOS.
