SONDIQ review
A flexible web mastering service for occasional users who want previews before paying.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SONDIQ is a web-based AI audio mastering service for musicians, AI music creators, podcasters, voice creators, and video producers. It analyzes dynamics, frequencies, and stereo characteristics, then lets users preview the result before downloading. Uploads can use WAV, MP3, FLAC, or AIFF files up to 200 MB, with support for sample rates up to 96 kHz. Its fit is strongest for solo creators and small teams that need occasional mastering rather than a broader production workspace.
Pricing is built around pay-per-track access and a Pro subscription. The published plans show a starting price of 1 for pay-per-track use, with MP3 320kbps export and a file available for 48 hours. Both access paths include unlimited previews, while Pro adds unlimited masters per month, WAV 16-bit export, AI mastering, and priority rendering. Subscribers also receive reference mastering, and the service supports WAV 24-bit exports depending on the plan. The unlimited preview workflow is particularly useful when comparing adjustable EQ, compression, stereo width, genre presets, loudness, and character settings before committing to a download.
SONDIQ is a focused choice for users who value adjustable automated mastering and want to hear the result before paying. It supports common audio upload formats and operates through the web, so it suits browser-based workflows without requiring a larger software installation. The trade-offs are important for regular production: there is no free plan, pay-per-track access provides MP3 rather than the higher-resolution WAV options, and the product is limited to the web with email support. Users needing desktop access, broader platform connectivity, or a free downloadable workflow should choose an alternative.
