Audio Converter Plus

If you need to convert MIDI to audio file then take a look on MIDIRenderer. It allows you to convert MIDI to MP3 just in one click and 100x faster than real-time recording.

Unmatched performance

Since the converter is designed to handle large sets of audio tracks, the speed is critically important. We carefully optimized it to work on the newest processors from Intel and AMD. The converter uses SIMD instruction sets, such as SSE3. Sound processing is divided into several parallel tasks, which allows you to get a performance gain on multi-core processors. Of course, all operations are performed without creating temporary files, as is done in many free converters.

Designed for Huge Audio Collections

Not every converter can process tens of thousands of songs in one pass, but not Audio Converter Plus. You can specify the root folder of your audio collection and the converter will scan all subfolders for supported audio files and playlists. Audio files can also be added from the Windows Explorer context menu or using Drag'n'drop.

Audio DSP

The heart of the converter is a high-quality DSP module that processes audio with 32-bit precision. It allows you to change the sampling frequency in a wide range, from 8000Hz to 96KHz. Audio DSP supports 8 bit, 16 bit and 24 bit audio resolution, as well as 32-bit floating point samples. In addition, it can analyze the volume level and perform normalization of the sound so that all your songs sound at the same volume.

Transferring Audio tags

The converter supports most modern metadata formats in audio files, such as ID3, APE tag, MP4 tags, WMA tags, Vorbis Comments. Tags for CD tracks are loaded automatically from GnuDB. After converting, all tags will be transferred to the output file.

Keep the directory structure

By default, the files are saved in the specified directory or in the directory where the source file is located, but the converter can determine the root folder and recreate the directory tree in the new location.

Batch Processing

No matter what format the original files have, now it's not your concern. The converter will automatically change the sampling rate, audio resolution, audio tag format and volume level according to the selected output format. If you want to leave some parameters unchanged, then select the option "Same as original" in the codec settings.


The converter is integrated with our other products. You can set them up and run directly from the Tools menu to record audio, edit music, edit tags or find the tempo of a musical composition.
