An audio channel mixer is a tool that manipulates the left and right channels of stereo audio. It can convert mono to stereo, stereo to mono, swap channels, extract individual channels, or adjust the stereo balance. This is useful for fixing reversed stereo recordings, creating mono podcasts from stereo sources, or isolating specific channels for analysis.
To convert stereo to mono, upload your audio file and select 'Convert to Mono' mode. The tool will combine both left and right channels into a single mono channel that plays equally through both speakers. This is ideal for podcasts, voiceovers, and situations where stereo information isn't needed.
Yes! Use the 'Swap Channels' option to fix reversed stereo recordings where the left sounds right and right sounds left. This commonly happens when microphones are connected incorrectly during recording. The swap function exchanges the left and right channels to correct the issue.
The balance control adjusts the relative volume between left and right channels without changing the overall volume. You can shift audio more toward the left speaker (-100%) or right speaker (+100%), with 0% being centered. This is useful for correcting unbalanced recordings or creating specific stereo effects.
Select either 'Left Channel Only' or 'Right Channel Only' mode. The tool will keep your chosen channel and mute the other, outputting the single channel as the audio. This is useful for isolating specific microphones in dual-mic recordings or extracting a particular track from stereo sources.
The channel mixer supports all common audio formats including MP3, WAV, AAC, OGG, FLAC, M4A, and more. The tool processes audio in your browser without uploading files to any server, ensuring your audio remains private and secure.
The channel mixer preserves your original audio quality. When converting formats or channel configurations, the tool uses high-quality processing algorithms. The only changes are to the channel structure itself (mono/stereo/balance), not to the audio fidelity or sample rate.
Absolutely! All channel mixing happens locally in your browser using client-side JavaScript. Your audio files are never uploaded to any server or transmitted over the internet. Your files remain completely private and secure on your device throughout the entire process.
