About formats

AIFF (Audio Interchange File Format) was developed by Apple in 1988, drawing its structural design from Electronic Arts' IFF standard. As an uncompressed audio container, AIFF stores linear PCM data at full CD quality — typically 16-bit at 44.1 kHz — preserving every detail of the original recording without lossy encoding. The format organizes content into chunks that can also carry metadata such as markers, instrument definitions, and comments. Professional audio engineers on macOS frequently rely on AIFF because it guarantees bit-perfect fidelity through every stage of editing and mastering. One significant advantage is zero generational loss: unlike MP3 or AAC, repeated saves never degrade the signal. Another strength is seamless integration with Apple's professional tools, including Logic Pro and GarageBand, where AIFF serves as a native working format. The container supports multiple sample rates and bit depths up to 32-bit, accommodating high-resolution workflows that exceed CD-quality specifications. For anyone prioritizing lossless integrity over storage efficiency, AIFF remains a dependable choice across the recording industry.

SNDR is the audio file format produced by Sounder, an early MS-DOS sound recording and playback utility from the early 1990s. Before Windows brought multimedia to the mainstream, Sounder was among a handful of DOS programs that let PC users capture and play audio through rudimentary hardware — often the PC speaker itself or early 8-bit sound cards. The format stores 8-bit unsigned PCM samples without any file header, relying on application defaults to determine playback parameters. Sample rates were typically low (4000 to 11025 Hz), reflecting hardware limits and storage costs when a 20 MB hard drive was considered generous. One practical advantage was absolute minimalism — with zero overhead bytes, every bit of the file was audio data, which mattered when storage was measured in kilobytes. The format could be piped directly to sound hardware without parsing, making real-time playback feasible on slow processors. Despite its simplicity, SNDR holds a place in computing history as one of the formats that brought digital audio to ordinary PCs. Files from this era occasionally surface in retrocomputing archives. SoX and ffmpeg can interpret SNDR files given the correct parameters, enabling preservation of early digital audio recordings.
