MIDI to Audio Converter

MIDI to Audio Converter turns your MIDI files into real audio: MP3, WAV, FLAC, M4A, AAC, OGG, Opus and AIFF. Everything is rendered on your device by a SoundFont synthesizer. It works offline, and your files never leave your device. BATCH CONVERTER • Add single files or whole folders including subfolders (drag and drop on Mac and Windows) • Converts several files in parallel, with progress and time left for each file • Choose the format, bitrate or bit depth, sample rate (22.05 to 96 kHz) and mono or stereo • Keep the folder structure and name the files with a template • Safe by design: your MIDI files are only read and existing files are never overwritten.
