How do I convert AIFF to SPHERE?

Upload an AIFF file to our converter, select SPHERE as the output, and press Convert. The system reads the AIFF's audio data and writes a SPHERE (.sph) file with the appropriate NIST header. You can then download the converted file instantly.

Why should I convert AIFF to SPHERE?

AIFF is primarily a consumer audio format for Mac, while SPHERE is the standard interchange format in speech processing and recognition research. Converting to SPHERE ensures compatibility with toolkits like Kaldi, HTK, and Sphinx, and is often required when working with telephone or voice-corpus datasets.

What technical data is preserved when converting AIFF to SPHERE?

For uncompressed PCM AIFF files, the converter preserves the sample rate, bit depth, number of channels, and audio sample values without lossy changes. For compressed AIFF variants such as MACE or ADPCM, the audio is decoded to linear PCM before wrapping in a SPHERE header; the original compression is removed, so the resulting SPHERE file is larger but playback remains faithful to the source.
