MixDiagnose

MixDiagnose is a web-based tool designed for music producers seeking to identify and correct mix issues before the mastering stage. The platform enables users to upload audio tracks in a variety of formats, including WAV, MP3, FLAC, MP4, MOV, and WebM, with files up to 50MB supported. Upon upload, MixDiagnose provides a severity-graded diagnosis of the mix, categorizing issues as Critical, Moderate, Minor, or Ideal. Users receive detailed recommendations specifying exact dB values and frequencies for each detected problem, and can choose to apply the suggested fixes in one click. The corrected file is then available for download as a single processed version with all selected changes applied.

MixDiagnose analyzes key aspects of a mix such as frequency balance, dynamic range, stereo width, headroom, clipping, loudness (LUFS), true peak, correlation, crest factor, and reference track match. The service allows users to compare their mix against genre-specific references, covering 18 genres including pop, hip hop, EDM, rock, jazz, trap, metal, Latin, country, Afrobeats, K-pop, classical, synthwave, and ambient. Additionally, users can upload a professional reference track for spectral comparison and A/B test their mix against the reference. The platform also checks for platform compliance, assessing whether the mix meets loudness standards for streaming services such as Spotify, Apple Music, YouTube, Tidal, Deezer, Amazon Music, Bandcamp, as well as club, radio, and other playback environments.

The tool operates on a freemium model, offering three free mix analyses per month, with additional free analyses available by sharing reports. Paid plans are available: the Producer plan at $19 per month includes 50 analyses, while the Pro plan at $49 per month offers unlimited analyses, step-by-step fixes for every issue, and the ability to download corrected files. MixDiagnose emphasizes transparency in its diagnostic process, providing users with specific, actionable feedback rather than generic preset adjustments. The platform is accessible without requiring signup or credit card information for initial use, making it suitable for producers who want precise mix feedback before proceeding to mastering.
