FAQ

MPEG-TS (MPEG Transport Stream, ISO/IEC 13818-1) is the standard container format for audio and video transmission in digital broadcast systems: DVB-T/T2 (digital terrestrial television in Europe, Asia, and Latin America), DVB-S/S2 (satellite), DVB-C (cable), and ATSC (North American standard). It was designed specifically for transmission environments with packet loss, including error correction mechanisms and multiplexing of multiple channels in a single stream. When a TV recorder, a hard-disk DVB receiver, or DVB tuner card capture software saves a recording, it does so directly in TS format because it is the native format of the received signal.
It depends on the broadcast standard and country. In Europe with DVB: AAC-LC or HE-AAC for high-definition TV (HD), MPEG-1 Audio Layer II (MP2) for older standard-definition (SD) channels, and AC-3 (Dolby Digital) on channels with imported North American production content. In Latin America with ISDB-T: predominantly AAC-LC. In North America with ATSC: AC-3 (Dolby Digital) as the mandatory standard for HDTV, with MP2 on legacy SD channels. IPTV TS files may contain any combination of the above plus HE-AAC v2 and Opus.
Yes. Digital radio recordings in TS format (common in European DAB+ receivers and some DVB radio capture configurations) typically contain AAC-LC or HE-AAC audio. Extraction to MP3 is straightforward. For radio captured via DVB-T card in software like DVBViewer or TVHeadend, the resulting TS files are fully compatible with this converter.
Yes. Demultiplexing audio from the Transport Stream preserves the PCR (Program Clock Reference) and PTS (Presentation Timestamp) from the original audio stream, ensuring that the resulting MP3 has the same duration and timing as the original recording, without gaps or desync, even for multi-hour continuous broadcast recordings.
Yes, with nuances. Topfield and Humax recorders save in standard compatible TS format. Some TiVo models use proprietary variants of TS format (TiVo Container, .tivo extension) that require additional decryption tools before audio extraction. If the file has a .ts extension and was recorded with a standard European DVB receiver, compatibility is complete.
Yes. Conversion happens entirely in your browser. TV recordings, which may be hours long, are never transmitted to any server. Privacy is total regardless of file size.
Convert TS to MP3: extract audio from TV recordings and DVR
MPEG Transport Stream (TS) is the digital broadcast container format defined in ISO/IEC 13818-1 (MPEG-2 Systems, 1994). Unlike multimedia containers designed for stored files (such as MP4, MKV, or AVI), Transport Stream was designed for real-time transmission over channels with potential packet loss: coaxial cable networks, satellite signals subject to interference, and digital terrestrial transmissions subject to multipath and shadowing. TS architecture is based on fixed-length 188-byte packets, each with a program identifier (PID) that allows demultiplexing multiple audio, video, and data streams from a single broadcast multiplex. In the European DVB ecosystem (Digital Video Broadcasting), .ts files are the direct result of recording the DTT antenna signal, satellite receiver, or cable network without any re-encoding, making them maximum-quality sources for audio extraction. Hard-disk DTT recorders (Humax HDR, Topfield TF, Ferguson Ariva, Vu+), DVB-T/S tuners for PC (Hauppauge WinTV, TechniSat USB), and media server software like TVHeadend (Linux HTPC) save recordings in native TS format.
Audio tracks in TS files vary by broadcast standard and geographic region. In Europe under DVB-T2, high-definition channels transmit AAC-LC audio (MPEG-4 Audio, ISO/IEC 14496-3) sampled at 48 kHz, or HE-AAC (High-Efficiency AAC, SBR+PS) for channels with bandwidth constraints. Legacy SD channels from the original DVB-T still use MPEG-1 Audio Layer II (MP2, ISO/IEC 11172-3) at 192 or 256 kbps — the standard digital broadcast audio codec in Europe since the first DVB deployments in the UK (1998) and Germany (2002). Channels with North American content (imported series, movies) frequently include a secondary AC-3 (Dolby Digital, ATSC A/52) track with 5.1 surround audio in addition to the main stereo track. In ATSC (the North American standard dominant in the US, Canada, and Mexico before ATSC 3.0 adoption), AC-3 is the only mandatory audio codec for HDTV. Extracting any of these codecs to MP3 first requires demultiplexing the audio PID from the Transport Stream — an operation Convertir.ai performs in WebAssembly without requiring software installation.
The most common use case for TS to MP3 conversion in 2025 is creating podcasts or audio archives from recorded public broadcast content: documentaries from BBC Two or BBC Four captured with a DVB-T UK tuner, NPR programs recorded via ATSC tuner, radio broadcasts in digital format recorded with DAB+ receivers or SDR (Software Defined Radio) devices. The typical workflow is: (1) record the broadcast with the DTT receiver's PVR or with software like Kodi, TVHeadend, or DVBViewer in native TS format; (2) convert the TS to MP3 to get the broadcast audio in an editable format; (3) edit the MP3 in Audacity, Adobe Audition, or GarageBand to remove ad breaks, add intro and outro, and normalize audio levels. Convertir.ai eliminates the friction of step 2, which historically required FFmpeg installed on the command line (ffmpeg -i recording.ts -q:a 0 -map a audio.mp3), democratizing the process for any user without technical knowledge while preserving recording privacy by processing locally.
