Auphonic is an automated audio post-production service trusted across the podcast world. Upload a recording and its AI applies the polish that used to require an audio engineer: intelligent leveling between speakers, loudness normalization to platform standards (podcast, YouTube, broadcast), noise and hum reduction, and filtering — all automatically.

Advanced features include multitrack processing, automatic speech recognition…

Coqui TTS is one of the most complete open-source text-to-speech toolkits — a library that lets developers run, train and fine-tune speech synthesis models on their own hardware, with support for dozens of languages and voice cloning from short samples.

Born from Mozilla's TTS research, Coqui packages state-of-the-art architectures behind a usable Python API: generate speech in 1,100+ languages via massively multilingual models, clone a voice from seconds of reference audio (XTTS), stream with low latency, and train custom voices on your own datasets. Because it runs locally, audio never leaves your infrastructure — the privacy and cost profile commercial APIs can't offer at scale.
