About formats

3G2 (3GPP2 file format) is a multimedia container developed by the 3rd Generation Partnership Project 2 for use on CDMA2000 mobile networks. Built on the ISO base media file format (MPEG-4 Part 12), it stores video encoded with H.263 or MPEG-4 Visual alongside audio in AMR, EVRC, or AAC codecs. The specification was first published in December 2003 to provide a standardized way for CDMA-based phones and networks to handle multimedia messaging and video playback. 3G2 files are engineered for extremely low-bandwidth conditions, achieving playable video quality at bit rates as low as 30-60 kbps. This makes the format especially efficient for mobile video capture on devices with limited processing power and storage. The container supports multiple tracks, timed text for subtitles, and embedded metadata. One significant benefit is near-universal compatibility with CDMA handsets from the mid-2000s era, ensuring reliable playback across a wide range of mobile devices. Though newer formats like MP4 have superseded 3G2 for most purposes, it remains useful for working with legacy mobile content and for situations where minimal file size is the primary concern.
Initial release: December 2003
SMP is the native file format of SampleVision, a sample editing application developed by Turtle Beach Systems around 1990. SampleVision was among the first PC-based visual sample editors, letting musicians view waveforms on screen and perform cut, copy, paste, and loop-point editing — capabilities previously limited to expensive dedicated hardware samplers. The SMP format stores 16-bit mono PCM audio along with sampling-specific metadata: loop start and end points, sustain loops, release loops, and MIDI root note assignments. This made SMP files directly useful for creating and exchanging patches between hardware samplers via MIDI Sample Dump Standard (SDS) transfers, which SampleVision automated through its interface. A primary advantage was bridging the PC world with professional sampling hardware from Akai, E-mu, Ensoniq, and Roland — devices that had tiny screens and minimal editing tools. The format also supported common sample rates (22050, 44100 Hz) and brief text descriptions alongside audio data. Though Turtle Beach pivoted to gaming peripherals and SampleVision was discontinued, SMP files persist in vintage sample library archives and can be converted using SoX.

Frequently Asked Questions

What is the benefit of converting 3G2 to SMP?

SMP serves a specific niche in audio workflows. Converting 3G2 to SMP lets you use the content in specialized tools and platforms requiring this format.

What apps support SMP playback?

You can play SMP with Turtle Beach SampleVision and SoX for cross-platform access.

Can I batch convert multiple 3G2 files?

You can upload and convert multiple 3G2 files to SMP at the same time. Batch processing runs on our servers so your device stays free.

Does converting 3G2 to SMP lose quality?

Quality depends on the bitrate and codec settings you choose. Higher bitrates preserve more detail from the original 3G2 audio track.

Is the conversion private and secure?

Uploaded files are deleted immediately after conversion, and completed SMP downloads are removed from our servers within 24 hours for full privacy.

Do I need to install anything?

No downloads or plugins needed. The 3G2 to SMP converter runs entirely in your web browser — just visit convertio.tools and start converting.
