Need high quality output.
Hi Hiro,
We support the following:
For output: MP3, Linear PCM (WAV), μ-law, A-law, OGG Opus
For input (cloning): WAV, MP3, FLAC, OGG
For streaming, we recommend Linear PCM, it’s uncompressed and plays nicely with audio buffers.
You can find more on this in our Generating Audio documentation.
