Frequently Asked Questions
Are my audio recordings uploaded to an external server?
Never. All audio decoding, DSP resampling, and file encoding execute 100% locally in your web browser memory using the native Web Audio API. Zero bytes are ever sent over the network.
What audio formats can I convert?
You can upload any format supported natively by your browser, including MP3, WAV, AAC, M4A, OGG, WebM, and FLAC files. The tool extracts uncompressed audio buffers directly from browser memory.
What is 16-bit PCM WAV and why convert to it?
16-bit PCM WAV is the universal uncompressed audio standard. It preserves pristine studio audio fidelity without lossy compression artifacts and is universally compatible across Windows, macOS, iOS, Android, video editors, and audio hardware.
How does mathematical resampling work?
The converter utilizes browser OfflineAudioContext DSP engines to resample audio rates (e.g. from 44.1 kHz to 48 kHz broadcast standard) cleanly without altering audio pitch or causing digital distortion.
Can I downmix stereo recordings to mono?
Yes! The channel selector allows you to force stereo, keep the original layout, or downmix left and right channels to a single balanced mono channel.
