To utilize eMastered, users first upload their unmastered audio files. The platform supports common formats like .AIFF, .WAV, and .MP3, with a file size limit of 900 megabytes. For best results, it is recommended to prepare your song by preventing clipping, ensuring the master channel remains between -3 and -6 dB. Exporting audio in the highest possible format, such as 48 kHz sample rate and 32-bit depth, is also advised. Upon upload, the AI-powered engine analyzes the track's sonic identity, genre, and structure. It then applies professional mastering techniques, including equalization, compression, and limiting, to optimize the sound. This process makes tracks louder, crisper, and more dynamically engaging. Users can preview an unlimited number of mastered tracks for free to assess the improvements. Downloading the final mastered versions typically requires a paid plan. Paid plans also unlock advanced mastering options, allowing users to adjust parameters like EQ, compression, stereo width, and volume for customized results. While each web instance masters one song at a time, there is no limit to the number of songs a user can master by opening multiple browser tabs. eMastered also extends its functionality to include features like AI distribution and stem separation, aiming to be a comprehensive audio production hub under a single subscription, simplifying the entire production and release process for artists and producers.
