About formats

MOD is a video recording format developed by JVC and used in hard disk drive and flash memory-based camcorders, particularly the JVC Everio series that debuted in 2004. The format stores standard-definition MPEG-2 program stream video alongside MPEG-1 Layer II or Dolby Digital audio, producing files that are structurally similar to VOB files found on DVDs. This similarity to DVD-Video data means MOD files can often be played or processed by tools designed for MPEG-2 content, sometimes requiring only a file extension rename. JVC designed MOD as a practical bridge between tape-based DV recording and fully file-based workflows, allowing users to record directly to removable storage for immediate computer access without tape capture delays. The format records at standard definition resolutions of 720x480 (NTSC) or 720x576 (PAL) at bit rates sufficient for consumer home video quality. MOD files are organized alongside metadata in a directory structure on the recording device that tracks clip information, recording dates, and playlist data. Panasonic and Canon also adopted the MOD format in some of their consumer camcorder models, extending its reach beyond JVC products. While the shift to high-definition recording has largely phased out MOD for new production, the format remains relevant for accessing and converting archived footage from the mid-2000s generation of file-based camcorders.

SLN (Signed Linear) is a headerless raw audio format storing 16-bit signed linear PCM samples at 8000 Hz mono, most closely associated with Asterisk — the open-source PBX framework developed by Digium (now Sangoma Technologies). Within Asterisk, SLN serves as the native internal audio representation: every codec transcoding operation passes through signed linear as an intermediate step. This makes SLN the backbone of Asterisk's codec translation architecture. The format contains nothing but raw samples — no headers, no metadata, no framing — so parameters must be known in advance. While this lack of self-description might seem limiting, it is actually an advantage in telephony where sample format is fixed by convention and every overhead byte matters across thousands of simultaneous channels. The 8000 Hz rate aligns with the G.711 standard for traditional telephony, capturing the full 300-3400 Hz voice band. Asterisk also supports extended variants (sln16, sln32, sln48) for wideband audio. SLN files require no decoding — just direct memory mapping — making them ideal for real-time mixing, conferencing, and prompt playback in high-density VoIP environments.

Frequently Asked Questions

Why convert MOD to SLN?

SLN provides Asterisk raw signed linear audio — convert when your workflow or target system specifically requires this audio format.

What plays SLN files?

Asterisk PBX, FreeSWITCH, and VoIP servers can handle SLN playback for audio listening and processing purposes.

Is audio quality preserved?

Quality depends on the encoding settings you choose. Configure parameters before converting to achieve your desired fidelity.

Can I adjust encoding settings?

Yes — set sample rate, encoding quality, and other options before conversion to tailor the SLN output to your needs.

Is extraction faster than video?

Audio extraction skips video processing entirely, so MOD to SLN conversion is faster than full video format changes.
