▍What is the sound-goods Audio Trimmer?

The sound-goods Audio Trimmer is a free browser-based tool for removing unwanted sections from any audio file — with no upload, no account, and no software to install. Processing runs entirely in your browser using the Web Audio API and lamejs. Your audio never leaves your device.

What makes it different from other online trimmers is its multi-region editor. Instead of only trimming the start and end, you can mark multiple sections anywhere in the file as "remove" zones. The waveform shows keep zones in pink and remove zones in red. The export stitches all keep regions into one continuous, clean output file — eliminating silences, coughs, false starts, or any unwanted segment in a single pass.

How it works: The audio buffer is decoded into raw PCM samples. Remove regions define sample ranges to skip. The export collects all samples outside those ranges in order, applies fade in/out at the boundaries of the final selection, encodes the result to 192kbps MP3 via lamejs, and downloads it. Nothing is sent to any server.

▍How to trim audio — step by step

Drop your audio file
Drag and drop an MP3, WAV, OGG, FLAC, or M4A file onto the trimmer above. The waveform renders immediately. Nothing is uploaded.
Select what to KEEP with the pink handles
Drag the left and right handles on the waveform to define the primary selection — the region you want to keep. The start and end times update in the inputs below. You can also type exact times directly into the Start and End fields for millisecond precision.
Mark sections to REMOVE (optional)
To remove a section from the middle — a cough, a silence, a false start — drag the handles to that section and click + Mark as REMOVE. The zone turns red on the waveform. Repeat for every section you want to cut out. Remove zones can be deleted individually from the list below the waveform.
Preview on loop
Enable Loop preview and click Play to hear your selection on repeat. Adjust the handles while it plays — ideal for finding the exact cut point without exporting. Use Zoom up to 20× for precise handle placement on long files.
Add fades and export
Set Fade in and Fade out durations (0–10s) if you want the audio to ramp up or down at the edges. Click Export MP3 to encode and download your trimmed file at 192kbps.

▍Common use cases

Removing silence and dead air from recordings

Long pauses, pre-roll silence, and dead air at the start or end of a recording are the most common trimming task. Select the actual content with the pink handles, ignoring the silence at each end, and export. The exported file starts and ends exactly where you set the handles.

Cutting out coughs, mistakes, and interruptions

For podcast editing, voice recordings, and interviews, use the multi-region remove feature to mark each unwanted moment — a cough at 1:23, a phone ringing at 4:07, a long "um" at 8:44. Each marked zone turns red. The export skips them all in one pass and joins the remaining audio seamlessly.

Creating a social media clip

Trim a longer recording to exactly the 15, 30, or 60 seconds needed for Instagram, TikTok, or YouTube Shorts. Use zoom to find the exact beat or word where you want the clip to start and end. Add a 0.5-second fade out so it doesn't cut abruptly.

Cleaning up a voice note or memo

Voice notes often start with button clicks, rustling, and "hello?" before the actual message. Trim the pre-content and post-content noise to keep only the useful audio. Because no upload occurs, private voice memos never touch a server.

Preparing audio for transcription

Transcription services and AI tools perform better on clean audio. Trim silences longer than a few seconds, remove background noise sections, and export a tight, clean file before sending to a transcription tool.

Making a ringtone

Select the hook or chorus of a song (20–30 seconds), add a 1-second fade in and 1.5-second fade out, and export. The result is a clean ringtone-ready MP3 that works on Android directly and can be converted to M4R for iPhone.

No. All processing runs locally in your browser using the Web Audio API. Your audio never leaves your device at any point.
Trimming removes the beginning or end of a file. Cutting removes a section from the middle. sound-goods does both — and allows multiple cuts and trims in a single export operation.
Yes. Click Play to hear the current pink selection. Enable Loop to hear it on repeat while you adjust the handles in real time — ideal for finding the exact cut point without exporting multiple times.
MP3, WAV, OGG, FLAC, and M4A as input. All exports are 192kbps MP3.
No server limit exists because nothing is uploaded. Files up to 500MB work reliably on most modern computers.
