MIDI to MP3 easily and quickly converts MIDI music to MP3, WAV, AIFF, FLAC, or M4A format. Automatic volume adjustment, audio effects, format customization, an easy-to-use interface, batch processing, automatic tag creation, and the ability to export to the Apple Music app or iTunes will enable you to quickly convert your favorite MIDI music to MP3 or another popular audio format with high-quality output audio.
FORMATS
MIDI to MP3 converter accepts and encodes "Format 0" and "Format 1" files to customizable MP3, WAV, AIFF, FLAC, or M4A formats.
EASY AS "ONE, TWO, …"
Drop .mid files or folders into any of the app's windows or directly onto the app's icon to start the conversion. The MIDI to MP3 converter will estimate the conversion time and provide details of the progress made on every source file. You will be informed when the conversion of all files is finished.
BATCH CONVERSION
The MIDI to MP3 converter enables you to convert an unlimited number of songs and folders with a single click, supporting multiple conversions simultaneously. Additionally, MIDI to MP3 can replicate the directory structure of the source folders. Therefore, it is incredibly convenient if you need to encode the entire MIDI music collection to MP3 or another audio format.
AUTOMATIC OUTPUT SETTINGS
MIDI to MP3 automatically estimates Bit Rate, Sample Rate, and Channels and applies optimal settings to output MP3, WAV, AIFF, FLAC, or M4A audio files. As a result, it guarantees the best possible sound quality and saves your time and hard drive space.
To convert to a specific bit rate, audio channels, and other settings, adjust the Format settings.
SOUND QUALITY
You can customize audio effects to improve output sound quality:
• Adjust the volume of tracks that are too quiet.
• Trim silence.
• Apply fade-in and fade-out effects for a smoother playback.
INTEGRATION WITH ITUNES / APPLE MUSIC

Just like the Old Quicktime
Jackson Drechsler
The output files sound as good as the old quicktime instruments on MacOS Tiger on the G4 processor.
Love it
Artzy_lady
Quick, easy and better quality than some other more expensive apps. I went thru four other purchases before I found the right one to convert Yahama electric piano midi files to mp3 with enough quality to sound almost as good as the piano it came from. Some of the other apps converted the files, but the quality of the sound was so awful it was tough to listen to. This one was just the ticket! Kudos for a quality app.
Not bad at all..

Not the most visually charming application, but I needed a utility to quickly convert a few old MIDIs to something I could rock on my phone, and this app did the conversion without complaint, and normalized the volume along the way. In and out without any fuss. Thanks.
