Settings

Select the bitrate range for the Variable Bitrate (VBR) MP3 file. Note that some legacy audio players may display incorrect audio file duration if VBR mode is used, in this case use CBR mode instead.
Set the constant bitrate for the audio track. Leaving this setting to "Auto" will automatically choose a bitrate to achieve a decent quality based on the source audio.
Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).

IRCAM sound files originate from the Institut de Recherche et Coordination Acoustique/Musique — one of the world's foremost computer music laboratories, founded by composer Pierre Boulez in Paris. The format was created in the early 1980s to serve the research needs of IRCAM and has since been adopted by academic and artistic communities working at the intersection of science and sound. An IRCAM file begins with a 1024-byte header containing a magic number, sample rate, channel count, and an encoding type field that supports linear PCM (16/32-bit integer and 32-bit float), mu-law, and A-law variants. The header block also accommodates free-form annotation text, allowing researchers to embed experiment metadata directly in the audio file. Because the payload is uncompressed by default, recordings maintain full fidelity through successive analysis and resynthesis cycles — essential in psychoacoustic experimentation. Software such as Csound, libsndfile, and SoX reads and writes the format natively. Key advantages include a well-defined header that eliminates parsing ambiguity, support for floating-point samples essential in scientific DSP work, and deep roots in the computer music community ensuring continued tooling.

MP3 (MPEG-1 Audio Layer III) is one of the most widely used digital audio encoding formats. It uses a form of lossy data compression to significantly reduce file sizes while retaining near-CD-quality sound, typically achieving a 10:1 compression ratio. Developed by the Fraunhofer Society in collaboration with other digital scientists, the format became an international standard in 1993 as part of the MPEG-1 specification. MP3 files can be encoded at various bit rates, commonly ranging from 128 kbps to 320 kbps, allowing users to balance file size and audio fidelity. The format's efficient compression, broad device compatibility, and small file sizes made it the driving force behind the digital music revolution, enabling practical music storage and distribution over the internet. Today, MP3 remains one of the most universally supported audio formats across virtually all media players, operating systems, and portable devices.
