Batch conversion is supported — queue multiple recordings and process them with one click.TS (MPEG-2 Transport Stream, ISO/IEC 13818-1, standardized July 1995) is the container DVRs, satellite receivers, IPTV set-top boxes, and HDHomeRun network tuners write to disk. Audio inside is usually AC-3 (Dolby Digital) for ATSC broadcasts in North America, MPEG-1 Layer II or HE-AAC for DVB in Europe — none of which are ideal source material for editing. AIFF, developed by Apple in 1988 from Electronic Arts' IFF container, holds uncompressed PCM that opens natively in Logic Pro, GarageBand, Final Cut Pro, and Pro Tools without the codec decode step.
| Property | TS (audio track) | AIFF |
|---|---|---|
| Container | MPEG-2 Transport Stream (188-byte packets) | IFF-based chunk container |
| Typical audio codec | AC-3, MP2, HE-AAC, E-AC-3 | Uncompressed PCM (signed integer) |
| Compression | Lossy | Lossless (none) |
| Standardized | July 1995 (ISO/IEC 13818-1) | 1988 (Apple, revised 1989) |
| Carries video? | Yes (primary use) | No (audio only) |
| Native macOS support | Plays in QuickTime/VLC; not a DAW import format | First-class — Logic, GarageBand, Final Cut |
| Typical use | Broadcast, IPTV, DVR captures | Studio editing, sampling, archival |
| File size for 1 hr stereo @ 48 kHz | ~150–250 MB (AC-3 at ~400 kbps) | ~660 MB (16-bit) / ~990 MB (24-bit) |
| Sample Rate | Bit Depth | Use Case | ~Size / hour stereo |
|---|---|---|---|
| 44100 Hz | 16-bit | CD mastering, podcasts | 605 MB |
| 48000 Hz | 16-bit | Broadcast/video alignment | 660 MB |
| 48000 Hz | 24-bit | Hi-res mixing, FCP delivery | 990 MB |
| 96000 Hz | 24-bit | Archival, oversampled editing | 1.98 GB |
Need a smaller lossless option? Convert to FLAC instead via TS to FLAC — same bit-perfect audio at 40–60% smaller files. For lossy delivery formats, see TS to MP3 or TS to M4A.
The original TS audio was lossy-compressed (AC-3, MP2, or AAC) at 128–448 kbps. AIFF stores uncompressed PCM at roughly 1411 kbps for 16-bit/44.1 kHz stereo or 2304 kbps for 24-bit/48 kHz. A 200 MB hour-long TS recording typically expands to 600–1000 MB of AIFF, depending on bit depth and channel count. That's expected — you're trading storage for an editor-friendly, generation-stable file.
Standard AIFF holds uncompressed big-endian PCM only. AIFF-C (the "compressed" variant introduced in 1991) can carry compressed audio inside the same chunk structure — including the "sowt" little-endian PCM variant macOS uses internally. xConvert outputs standard uncompressed AIFF, which is the safest choice for cross-platform interchange and DAW import. If a tool refuses your AIFF, it usually wants AIFF-C/sowt — re-save inside the DAW.
Only the decode step is lossy, and that loss was baked in when the broadcaster encoded the AC-3/AAC track — converting to AIFF doesn't add new loss. After that one decode, every subsequent save, edit, or copy is bit-perfect PCM. That's why AIFF beats re-encoding to MP3/AAC for any workflow that involves multiple edit passes.
WAV and AIFF carry identical PCM audio data — the difference is the container. AIFF uses IFF-style chunks (Apple-friendly) and supports richer metadata: ID3-style tags, MIDI notes for sample mapping, loop points for samplers, and instrument chunks. Logic Pro and the EXS24 sampler read AIFF metadata that WAV ignores. If you're on Windows-only workflows, TS to WAV is functionally equivalent.
Yes — open the Trim option, set a start time (HH:MM:SS.ms) and duration in seconds, and only that slice gets converted. Useful for grabbing a single song from a recorded radio broadcast or one quote from a captured news segment without processing the whole hour.
The default first audio track in the TS program map is converted. Multi-track demuxing isn't exposed in the web UI — for selective track extraction from a multi-language TS, the FFmpeg command line (ffmpeg -i in.ts -map 0:a:1 -c:a pcm_s16be out.aiff) gives per-stream control.
No. This converter targets the audio stream only — the H.264/MPEG-2 video track is discarded by design (AIFF is an audio-only container). If you need the video preserved, convert to TS to MP4 instead, which keeps both streams.
Match the source: ATSC/DVB broadcasts almost always carry 48000 Hz audio, so leaving the rate at Original (which preserves 48 kHz) avoids any resampling artifacts. Pick 44100 Hz only if your downstream tool requires CD-rate audio, and 96000 Hz only if you genuinely have hi-res content (most broadcasts don't — upsampling adds zero new information).
