About formats

TS (MPEG Transport Stream) is a standard container format specified as part of the MPEG-2 systems layer (ISO/IEC 13818-1), standardized by the Moving Picture Experts Group in 1995. Transport streams are designed for communication and storage environments where data loss or corruption is possible, such as broadcast television, satellite transmission, and network streaming. The format divides content into fixed-size 188-byte packets, each carrying a 4-byte header with synchronization, error indication, and stream identification information. This packet structure enables receivers to rapidly resynchronize after signal interruptions, a critical capability for real-time broadcast delivery that distinguishes transport streams from program streams designed for reliable storage media. TS can multiplex multiple programs into a single stream, with Program Specific Information (PSI) tables describing the structure and content of each program. The format supports virtually any audio and video codec, though it most commonly carries MPEG-2 video, H.264, or HEVC alongside AAC, AC-3, or MPEG audio. TS is the backbone of digital television delivery worldwide, used by DVB, ATSC, and ISDB broadcasting standards as well as IPTV and OTT streaming services utilizing HTTP Live Streaming (HLS). Resilience, standardized structure, and broad codec support make TS equally at home in live broadcast chains and file-based recording workflows.

AU is an audio file format introduced by Sun Microsystems for its Unix workstations and the NeXT platform. It features a minimal 24-byte header specifying data offset, size, encoding type, sample rate, and channel count, followed by the audio payload. AU supports numerous encodings, including uncompressed linear PCM at various bit depths, mu-law and A-law companding (logarithmic compression used in telephone systems), and several ADPCM variants. This versatility made AU a workhorse across early Unix environments, web audio (Java applets defaulted to AU), and telephony applications. One advantage is simplicity: the compact header and straightforward structure make it trivial to parse, generate, and stream programmatically. The built-in mu-law option provides another benefit, delivering reasonable voice quality at just 8 KB per second — half the rate of 16-bit uncompressed audio — invaluable when storage and bandwidth were scarce. Although modern formats have largely supplanted AU in consumer applications, it retains a foothold in scientific computing and audio processing pipelines where minimal overhead and reliable cross-platform behavior are valued.

Frequently Asked Questions

Why convert TS to AU?

AU provides Sun/NeXT AU format for Unix and Java audio workflows. Converting extracts compatible audio data from your TS broadcast recordings.

What software handles AU?

Specialized audio tools, SoX, and format-specific applications handle AU files for playback and processing.

Is AU widely supported?

AU serves specific use cases. For general audio, MP3, WAV, or FLAC are more broadly compatible.

Can I adjust settings?

Yes — configure sample rate and encoding parameters before converting to match your target system.

Is batch conversion available?

Upload multiple TS files and extract AU audio from each simultaneously in one session.
