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.

Initial release: 1988
IMA ADPCM (Adaptive Differential Pulse-Code Modulation) is a compact audio coding standard published by the Interactive Multimedia Association in 1992, addressing the need for a lightweight, royalty-free compression scheme suitable for early multimedia PCs and embedded devices. The algorithm encodes each sample as a 4-bit nibble representing the quantized difference from the previous sample, while an adaptive step-size table adjusts dynamically to track signal amplitude — delivering a fixed 4:1 compression ratio over 16-bit PCM. Decoding requires only an integer multiply-add per sample and a small lookup table, so even modest 1990s CPUs could decompress in real time without dedicated DSP. The format became deeply embedded in the multimedia landscape: Microsoft adopted it as a standard ACM codec for WAV files, game engines relied on it for sound effects, and telephony equipment used it for voice storage. Its advantages are enduring: predictable 4:1 size reduction simplifies buffer allocation in constrained environments, the decode path runs on 8-bit microcontrollers, and the open specification made IMA ADPCM one of the most broadly implemented audio codecs in computing history.

Frequently Asked Questions

Why convert AIFF to IMA?

IMA ADPCM offers compact encoding. Convert AIFF when your system requires headerless ADPCM audio data.

What programs can open IMA files?

SoX and raw audio editors handle IMA ADPCM data. It requires proper parameters for correct playback.

Is batch AIFF to IMA conversion supported?

Absolutely. Upload multiple AIFF recordings at once and convert them all to IMA format in parallel.

How long does AIFF to IMA conversion take?

Audio conversions typically complete within seconds. Larger files may take a bit longer depending on size and server load.

Are my files safe when converting AIFF to IMA?

Completely. Source audio is erased right after processing, and converted IMA files are purged within 24 hours.

Can I convert AIFF to IMA on my phone?

Yes — the converter runs in any mobile browser. Works on both iOS and Android without installing an app.
