.ts recordings, or click "+ Add Files" to browse. Batch conversion runs every file through the same settings.TS (MPEG-2 Transport Stream) is a broadcast container — 188-byte packets designed to survive over-the-air, satellite, and IPTV networks. It usually wraps AC-3, MP2, or AAC audio alongside an H.262 or H.264 video stream. MP3 strips out the video and packaging entirely so the audio plays anywhere a generic media file does.
.ts. Pulling the audio to MP3 turns a 2 GB hour-long episode into a ~30 MB file you can drop into a phone or car stereo..ts chunks. Once you've concatenated them you can convert the result to MP3 for podcast-style listening of live shows, lectures, or sermons..ts (or .m2ts). MP3 makes the soundtrack portable for editing, transcription, or background-music reuse.| Property | TS (Transport Stream) | MP3 |
|---|---|---|

A .ts file is a container with both video and audio inside, plus broadcast-layer headers and error-correction padding. The MP3 keeps only the audio track and re-encodes it efficiently, so a 2 GB hour-long HD recording typically shrinks to 30-150 MB depending on the bitrate you pick.
Re-encode. The audio inside a TS file is almost always AC-3, MP2, or AAC — not MP3 — so a true demux to MP3 isn't possible. The converter decodes the source stream and re-encodes it to MPEG-1/2 Layer III at the bitrate and sample rate you choose. Picking 192 kbps or higher keeps the loss inaudible to most listeners.
For broadcast TV (AC-3 at 192-384 kbps) and dialog-heavy content, 128 kbps CBR is usually indistinguishable from the source. For music videos, concert recordings, or anything you'll listen to on headphones, jump to 192-256 kbps. Use 320 kbps only if the MP3 is itself a master you'll re-edit later.
If you have a folder of numbered .ts chunks from an HLS stream, upload them all and they'll be processed individually. To get one continuous MP3 you'll usually want them concatenated first; some users merge them by binary concat (HLS TS chunks are designed to splice cleanly) before uploading. Once merged, run that single file through this tool.
MP3 itself supports stereo and joint stereo but not multichannel surround. When the source is AC-3 5.1 or DTS 5.1, the converter automatically downmixes to stereo using standard Lt/Rt coefficients. If you'd rather keep the surround channels, convert to a multichannel-capable format like AAC or WAV instead.
Yes — for spoken-word audio, Mono + 96 kbps + 22050 Hz produces files about a third the size of stereo 192 kbps with no perceptible quality loss for dialog. Music or anything with stereo imaging should stay at 44100 or 48000 Hz stereo.
Yes. Open the Trim option and set the start time and duration in HH:MM:SS format — for example start 00:14:30 duration 00:21:00 extracts a 21-minute segment starting 14:30 into the file. Only the trimmed range is encoded, so a single short clip from a multi-gigabyte recording finishes in seconds.
.mts and .m2ts are AVCHD and Blu-ray flavors of the same MPEG-2 Transport Stream container, with slightly different headers and a 192-byte packet size (188 + 4-byte timestamp). The audio extraction process is identical — if your file is from a camcorder or Blu-ray, use MTS to MP3 instead and the settings here map across exactly.
Run the file twice: once through TS to MP4 for the video, then back here for the audio. Or pull the audio first as MP3 and pair it back to the trimmed MP4 in a video editor. For just chopping the resulting MP3, use the audio cutter instead of re-running the full conversion.
