Transport Stream recordings from DVB, ATSC, or IPTV sources carry compressed audio (typically MPEG-2 Audio or AC3) embedded within 188-byte packet streams. Converting TS to AIFF decodes this broadcast audio and wraps it in Apple's uncompressed Audio Interchange File Format — the professional audio standard used in Logic Pro, GarageBand, and Pro Tools on macOS.
AIFF stores audio as uncompressed PCM, preserving every sample without lossy artifacts. This matters when you need broadcast audio for professional editing, sound design, or forensic analysis where lossy compression would destroy detail. AIFF is also the native format for macOS audio workflows, ensuring zero compatibility issues with Apple's creative tools.
The TS demuxer reads packet headers to locate audio PIDs and reassembles complete audio access units from potentially out-of-order packets. The audio decoder (MPEG-2 Audio or AC3/A52) outputs raw PCM samples, which are written directly into an AIFF container with big-endian byte ordering. The output preserves the source sample rate (48 kHz for broadcast) and bit depth (16-bit or 24-bit depending on source precision).
AIFF is mathematically lossless from the decoded PCM — you get every sample the broadcast decoder produces. However, the source audio in a TS file was already compressed (MPEG-2 Audio at ~192-384 kbps or AC3 at 192-640 kbps), so AIFF preserves the quality ceiling of that original encoding. No additional quality is lost in the conversion.
