Frequently asked questions
How do I select mono or stereo output?
Choose mono or stereo and generate MP3 or WAV. Mono can suit single-channel speech; choose stereo when you want to retain an existing left/right difference.
Why can stereo sound quieter when converted to mono?
Mono combines left and right signals. Opposite-phase sound can partly cancel and become quieter or hollow. Listen to the result rather than judging suitability only by the channel count.
Does converting mono to stereo create spatial sound?
No new spatial information is created; the mono signal appears in two channels. This is not surround-sound creation, vocal separation or automatic instrument placement.
Can mono conversion keep only the left or right channel?
This tool mixes channels for mono and does not offer a left-only or right-only selection. Listen to the export when a source records sound on only one side.
Is mono always half the size of stereo?
No. WAV at matching sample rate, duration and bit depth can shrink substantially. MP3 uses a fixed bitrate here, so changing channels does not guarantee half the file size.
What size and duration limits apply to Audio Channel Converter?
Audio input is limited to 10 MB and 30 minutes, with generated output up to 150 MB. WAV can be much larger than an MP3 source; choose MP3 or a shorter track if needed.
