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.
Demixr
Demixr is a web service for processing audio, with tools for separating vocals and instruments, removing reverb, marking speech, and analyzing BPM and key. Its Pro 1.5 vocal separation has Voice mode for complex mixes, live recordings, or speech over music, and Music mode for songs and covers or separating vocals from accompaniment. A separate stem tool uses Demucs to split music into vocals, drums, bass, and other parts. For dereverb, Demixr recommends isolating vocals first; applying the effect to a mixed track can cause artifacts or distortion. VAD provides editable speech-segment markers and batch export, though detection may be inaccurate with quiet vocals or noisy recordings. BPM analysis includes tempo, key, and Camelot values, with optional tap-to-sync. The free plan costs nothing and includes 10 minutes of audio monthly, a 10 MB upload limit, two VAD uses, queued processing, and no WAV downloads. Paid one-time plans start at $4/mo, without automatic renewal. Uploads and outputs are deleted within 24 hours by default.
