The AI Voice Generator supports both WAV and mp3 audio formats. You can export all the text segments as separate individual mp3 or WAV files or merge and download the text into a single mp3 audio file.
Merging to a single WAV file is not supported, but you can convert your merged mp3 file to WAV using third-party services.
All commercial voices use the highest speech-generated audio quality in the industry now at 44.1 kHz.
Frequency or bitrate cannot be changed in-app, but there are many free online resources you can use to convert your downloaded audio files.
Frequency and bitrate for WAV files can be converted here.
Frequency and bitrate for mp3 files can be converted here.
