In their own words
AudioShake
AudioShake separates and processes audio for creators and developers. Studio can split music into vocal and instrument stems or divide finished mixes into dialogue, music and effects. Multi-Speaker separates overlapping voices into labelled tracks, while Speech Recovery denoises and de-reverbs recordings to improve speech intelligibility. The browser-based Lyric Editor transcribes lyrics, aligns words with recordings and supports editing and realignment. Studio accepts WAV, AIFF, FLAC, MP3, AAC, M4A, MP4 and MOV files up to 2 GB. Developers can use REST API processing for batch or streaming workflows, with webhooks; a Local Inference SDK is offered for iOS, macOS, Android, Windows and Linux. Private inference can run in a customer's cloud or fully offline. The free plan starts with 200 credits, MP3 export and files up to 10 minutes. Starter costs $20 a month and Pro costs $40 a month; Enterprise pricing is custom. AudioShake focuses on lyric transcription, not general speech transcription.
StemDeck
StemDeck separates songs into stems for practice, study, transcription, remixing, and other creative audio work. Its Demucs htdemucs_6s model separates vocals, drums, bass, guitar, piano, and other sounds. Files accepted include MP3, WAV, FLAC, OGG/Opus, MP4, and M4A, and songs can also be supplied by YouTube URL. The workspace provides waveform lanes, mute and solo controls, volume adjustment, and looping; users can export individual stems or a custom mix in WAV or MP3. Song analysis includes BPM, key, scale, confidence, integrated LUFS, and sample peak level. StemDeck says audio processing runs locally and the app does not transmit, store, cache, or redistribute audio. Internet access is needed for YouTube downloads and an initial model fetch of about 170 MB, which is cached afterward. The project documents Docker and Unraid deployment, source-based web-server use, and a local REST API. It is free, with no account, quota, uploads, or subscription, but handles one job at a time, supports up to six stems, and has no mobile app.
