Our verdict on Songmastr

Songmastr is a web-based automated mastering service for musicians and producers. Upload a song or beat, then upload a custom reference track or select one from its catalog. Songmastr processes the audio to match the reference’s RMS, frequency response, peak amplitude, and stereo width. It accepts WAV and MP3 files, supports tracks up to 10 minutes and 80 MB, and provides downloadable mastered files without requiring software or registration. It is suited to solo artists and small production workflows that want quick reference-based mastering.

The pricing structure is built around free weekly use and one-time credit packs rather than monthly subscriptions. The free option provides up to seven masters per week. The Single Pack costs $4 one-time for 3 masters, with 3 different masters per song. The EP Pack costs $10 for 9 masters across 3 songs. The Album Pack costs $20 for 50 masters across 10 songs, while the Studio Pack costs $60 for 300 masters across 30 songs. Paid packs also include custom and catalog references plus uncompressed .wav files, with more variations per song at higher tiers.

Reference matching is Songmastr’s defining feature, covering four measurable aspects of the selected reference rather than offering a broad set of manual mastering controls. The service runs in the cloud through a web interface and provides email support. Its focused workflow fits artists who want to compare several reference-based results, download WAV masters, and avoid recurring charges. It is less suitable for engineers who need loudness-target controls, stem mastering, or broader input-format support. Artists seeking a simple reference-led workflow should consider Songmastr; projects requiring those controls should choose another mastering tool.
