Optivox masters spoken word audio automatically. You upload a recording, and Optivox measures it, cleans it up and masters it to the loudness standard your platform expects. There is nothing to install and no settings to learn.
The whole process runs in three stages. Most files come back in a few minutes, ready to publish as WAV or MP3.
Common questions
What kind of audio is Optivox built for?
Voice recordings: audiobook chapters, podcast episodes, interviews, voiceovers and video narration. Everything is tuned for speech rather than music, which is why the results hold up on long files with one or several speakers.
Will my audiobook meet ACX requirements?
The Audiobooks mode masters to the ACX window of -23 to -18 dB RMS with true peaks at or below -3 dB, and keeps the noise floor low enough to pass submission checks. Pick that mode before processing narration so the targets are applied.
What does Optivox actually change in my recording?
Background noise and hum are reduced, room reverb is dried out, tonal balance is corrected so the voice sits naturally, levels are evened out between speakers and across the file, and the final master is set to the loudness target for your platform. Breath reduction and filler word removal are optional.
How long does it take?
Usually a few minutes. Longer audiobook chapters take a little more, and you can leave the page while a file is processing. Finished files stay available to download for seven days.
Do I need any audio experience?
No. There is no timeline, no plugins and no dials to balance. You choose the type of recording, upload the file and download the finished master.
