MajorDecibel is an online instant audio mastering service operated by MajorDecibel Inc., aimed at independent musicians and bands. After users upload audio, the file is sent to its servers and processed by its in-house mastering engine within a few minutes. The website says the service has been running since 2015 and has processed more than 2 million tracks.
Its processing chain includes bass/sub-bass enhancement, stereo multiband compression, linear-phase EQ, gain and limiting, stereo enhancement, and more. Users can choose from three intensity levels: Low, Medium, and High. Higher intensity is louder and more punchy but sacrifices dynamics, while lower intensity preserves more dynamics. Post-mastering EQ offers five options—Warmer, Warm, Neutral, Bright, and Brighter—which can be switched and previewed before download for A/B comparison. For input, it supports most 44.1 or 48kHz mono/stereo audio files, recommends WAV, and supports 16-, 24-, and 32-bit WAV.
The free plan allows 1 track per month, has a 250MB limit, and does not require an account. However, the site is inconsistent about the free plan’s output formats: one place says MP3 only, while another mentions MP3, WAV, and HD WAV. The paid Unlimited Mastering Pass costs $45/year, equivalent to $3.75/month, and includes unlimited masters, files up to 1GB, Hi-Res MP3, FLAC, HD WAV, 24/7 access, instant downloads, and a commercial license. Users retain the rights to their tracks, may sell mastered works without attribution, and the platform only receives limited processing rights necessary to provide the service. Uploaded tracks are stated to be deleted from the servers within 48 hours.
The main advantages are its low barrier to trial, with 1 free master per month without registration; its annual pricing is relatively low among similar online mastering services; and the workflow is straightforward, making it suitable for quickly producing a releasable version. The downsides are that the company itself clearly states it cannot replace a professional mastering engineer; the service is developed and maintained by one person, so enterprise-level support, SLAs, and team workflows are unclear; and collaboration features are basically limited to email feedback and, with permission, social media showcases.
MajorDecibel is suitable for independent musicians on a limited budget who need to quickly improve the sound quality of demos or online releases. It is also useful for creators who want to compare different loudness and EQ directions. It is not suitable for projects that require human critical listening, complex revisions, or record-grade mastering. The main site does not state whether access from mainland China or local payment methods are supported, so this needs to be tested directly; prices are in USD, and payment channels are unknown. Alternatives to consider include LANDR, eMastered, BandLab Mastering, CloudBounce, and iZotope Ozone.
