AudioShake vs VocalDrop

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.

VocalDrop is a free desktop app that uses AI to separate vocals from songs stored on a computer. A separation can produce both an isolated vocal and an instrumental stem, for uses such as sampling, remixing, editing, or karaoke. Fast and Max modes use RoFormer-family models, with different models available for some hardware. The app can also extract audio from video, separate it, and place a selected stem back into a synchronized video. Users can paste links from YouTube, SoundCloud, Vimeo, TikTok, and more than a thousand other sites for fetching. Optional processing includes denoising, AI vocal restoration, silence removal, and audio-format conversion. The maker says track contents are processed locally and not uploaded. Separation can run offline after the required model download; enabling NVIDIA acceleration also downloads a one-time CUDA package. A command-line interface with JSON output supports pipelines. VocalDrop runs on Linux, macOS, and Windows, and its free plan lists no track limits, watermark, account requirement, or feature paywall. The maker says current builds are not code-signed or notarized and provides SHA-256 checksums for release assets.
