Audio Editor
Edit audio directly in your browser: cut waveform selections, join clips, change playback speed or volume, reverse a track, add or trim silence, and convert supported formats. Processing stays on your device, giving you a focused workspace for everyday audio edits without a server upload.

How to Edit Audio Online
Upload audio or video
Choose a supported audio file from your device or load a compatible video when you need to work with its sound. The track is decoded locally in your browser, making the workspace suitable for podcasts, music, voice memos, interviews, narration, and other everyday editing jobs without first sending the source to Pixwit.
Pick an editing tool
Choose the operation that matches your task. Cut a waveform range, append additional clips with a short crossfade, adjust speed or volume, reverse the recording, add silence to the beginning or end, remove long silent edges, or convert the result to another supported format. Preview important changes before export when possible.
Export your edited audio
Choose a supported output such as MP3, WAV, AAC, or FLAC and process the edit locally. Download the result when it is ready and test it in the application, device, or publishing workflow where you plan to use it. Keep the original source when you may need to make different edits later.
Audio Editing Tools in One Workspace
Private browser audio editor
Files never leave your device. This online audio editor uses Web Audio and WebCodecs in your tab, so recordings and client work stay off our servers.
Visual waveform cut
Drag handles on the waveform to set in and out points before export. The audio editor shows peaks and valleys so you can cut precisely without guessing timestamps.
Join clips in one editor
Merge podcasts, takes, or song parts with a short crossfade. Build a longer track from multiple files without opening a separate audio editor app.
Convert formats locally
Export MP3, WAV, AAC, FLAC, or wrap audio in MP4/WebM from the Convert tab. One audio editor covers trimming and format changes in a single workflow.
Essential Audio Editing Tasks Explained
Audio editing can mean anything from removing a few unwanted seconds to assembling several recordings into one track. A browser workspace is useful for focused jobs where you need clear controls and a quick export rather than a large production environment. The right operation depends on whether you are changing timing, structure, loudness, direction, silence, or file format.
Cut and trim waveform selections
Trimming is useful for removing an unwanted beginning or ending, extracting a useful passage, or shortening a recording. Use the waveform to locate speech, music, and silence, then listen around the selected boundary so you do not cut through a word or musical phrase. For more complex multi-segment trimming, the dedicated Audio Cutter provides a more focused timeline workflow.
Join multiple audio clips
Joining combines separate recordings into a longer track. This can help assemble interview sections, podcast takes, voice notes, music sketches, or sequential narration. A short crossfade can soften the transition between adjacent clips, but it is still worth checking volume and background ambience because two recordings captured in different conditions may not sound continuous automatically.
Change speed and volume carefully
Speed changes alter the timing of a recording, and the implementation on this page uses simple resampling, so pitch changes with speed as well. Volume adjustment changes level rather than repairing distortion or clipped source audio. Make moderate changes, preview the result, and preserve the original when the recording may later need more advanced processing in a DAW.
Reverse audio or manage silence
Reverse is useful for creative effects, sound design experiments, and inspecting how a clip behaves backwards. Silence controls solve a different problem: add quiet space when a recording needs padding, or trim long silent areas from its edges. Be careful with speech and music because a small amount of natural room tone can make an edit sound less abrupt.
Convert the edited result
Format conversion helps when the next application or device expects a particular file type. MP3 is convenient for compact distribution, WAV is common for uncompressed PCM workflows, and formats such as AAC or FLAC fit other compatibility and quality requirements. Conversion and editing are separate decisions, so choose the output based on what you plan to do with the file next.
What Can You Do with an Online Audio Editor?
Clean up podcasts and interviews
Trim an unnecessary intro or ending, remove a section you do not need, adjust overall volume, and join separately recorded parts into a single draft. Browser editing is useful for straightforward cleanup; difficult room echo, severe noise, clipping, or detailed mixing may still require dedicated production software.
Prepare voiceovers and narration
Shorten takes, remove extra silence, add a little quiet space where needed, and combine multiple narration clips in sequence. Check transitions with headphones before exporting because differences in microphone distance, room tone, and recording level can become more obvious when clips are placed next to one another.
Make quick music and sound edits
Extract a passage, join sketches, adjust level, reverse a sound for an effect, or create a different-format copy for another application. Keep a lossless or original source for future work whenever repeated processing could reduce quality or when you expect to continue mixing and mastering elsewhere.
Edit audio extracted from video
Compatible video files can provide the source audio for trimming, joining, speed changes, volume adjustments, reversal, silence management, or conversion. This is useful when you only need dialogue, narration, or another sound track and do not need to keep the visual portion in the exported audio file.
