Convert SF2 to AIF

Understanding SF2 and AIF file formats

SF2 (SoundFont 2) is a file format used for storing instrument sounds, samples, and presets, commonly used in MIDI music production. It allows musicians and producers to emulate real instruments using sampled audio data. AIF (Audio Interchange File Format), also known as AIFF, is an uncompressed audio file format developed by Apple, widely used for high-quality audio storage and editing on both Mac and Windows platforms.

Why convert SF2 to AIF?

Converting SF2 to AIF is useful when you want to use instrument samples from a SoundFont in audio editing software that supports AIF files, or when you need to process or share the audio in a more universally compatible format.

How to convert SF2 to AIF

Since SF2 files contain instrument samples and not direct audio, the conversion process involves extracting the samples or rendering MIDI sequences using the SF2 instruments, then exporting the result as AIF.

Recommended software for SF2 to AIF conversion

• Polyphone: A free SoundFont editor that allows you to export individual samples from SF2 files as AIF. Open your SF2 file, select the sample, then use File → Export → Sample and choose AIF as the output format.
• Audacity: Import MIDI and assign the SF2 as a soundfont using a VST plugin (like Sforzando), then render the MIDI to audio and export as AIF via File → Export → Export as AIFF.
• FL Studio: Load the SF2 in the DirectWave or Fruity SoundFont Player, play or sequence the instrument, then export the audio as AIF using File → Export → Wave file and select AIFF as the format.

Step-by-step conversion example using Polyphone

1. Download and install Polyphone from the official website.
2. Open your SF2 file in Polyphone.
3. Select the sample or instrument you wish to export.
4. Go to File → Export → Sample.
5. Choose AIF as the output format and save the file.

Tips for best results

• Ensure you are exporting at the desired sample rate and bit depth for optimal audio quality.
• If you want to convert entire MIDI performances using SF2 instruments, use a DAW (Digital Audio Workstation) to render the MIDI to audio before exporting as AIF.
