In their own words
SoundBoost.ai
SoundBoost.ai is an online audio mastering service for musicians, artists, and producers. It combines deep learning with LLM technology, letting users describe desired sound changes in natural language. The service also splits audio into vocals, drums, bass, and instruments; Unlimited Plus adds guitar and piano channels. Unlimited and Unlimited Plus include reference mastering. Finished masters can be downloaded as 24-bit WAV or 320 kbps MP3, and SoundCloud tracks can be imported by link. The free plan provides 10 revisions per project but does not allow finalizing or downloading. Free stem-splitting uploads have no daily or monthly count quota, though each file is limited to 1.5 GB and 22 minutes 30 seconds. Unlimited is listed at $48 a year, billed annually. One subscription works across the web, iPhone, iPad, and Android. Users retain ownership of their music and may monetize masters. SoundBoost says it does not train its AI on users' audio or share music with third parties without consent.
WhitePrint AudioEngine
WhitePrint AudioEngine provides AI-powered audio analysis and mastering through a web interface and API, returning analysis data, mastered audio, or both. Its BS.1770-4 analysis measures LUFS, true peak, loudness range, crest factor, spectral balance, and stereo width. Three independent AI models make mastering recommendations, and users can inspect each model's advice and the reasoning behind the consensus. The mastering chain has 14 hybrid DSP stages, bypassed by default unless the AI directs otherwise. Users can compare original and mastered audio with an A/B player, inspect metric changes, and download a WAV file. WAV and FLAC inputs are supported, and direct processing can use links from Google Drive, Dropbox, OneDrive, Amazon S3, and Google Cloud Storage; Suno and SoundCloud are also listed as URL sources. API routes support full mastering, analysis-only, deliberation-only, and DSP-only tasks. Submitted audio is deleted within 24 hours after job completion and is not used to train AI models. The free plan includes three WAV masters monthly and seven days of analysis history. Paid plan prices range from $54 a month to $5,506 a month.
