Set the overall output MP2 audio bitrate. If set to "Custom", the recommended range is ≥320 kbps with a maximum value of 384 kbps.
Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).
Set the sample rate of the audio. Music with a full spectrum (20 Hz — 20 kHz) requires values not lower than 44.1 kHz to achieve transparency. More info can be found on the wiki.

3gp

3GP is a multimedia container format defined by the 3rd Generation Partnership Project as the standard media format for 3G mobile services. Based on the ISO base media file format (MPEG-4 Part 12), it was designed to reduce storage and bandwidth requirements so that mobile phones with limited capabilities could efficiently capture, store, and play video content. The format typically uses H.263 or H.264 video codecs paired with AMR-NB, AMR-WB, or AAC audio. 3GP was instrumental in bringing multimedia to mobile devices during the early smartphone era, when network speeds and device hardware imposed tight constraints on file sizes. The streamlined container strips away overhead found in full MP4 files, resulting in significantly smaller files that stream reliably over slow 3G connections. 3GP supports both GSM and UMTS network protocols and includes provisions for timed text and still images within the container. Broad adoption by major handset manufacturers ensured that practically every 3G-capable phone could handle 3GP media natively. Although modern mobile devices now favor MP4 and other advanced formats, 3GP files are still encountered in archives of older mobile recordings and in regions where bandwidth-efficient video delivery remains important.

mp2

MP2 (MPEG-1 Audio Layer II), also known by its original project name MUSICAM, is a perceptual audio codec standardized as part of ISO/IEC 11172-3 in 1993. While its successor MP3 captured the consumer spotlight, MP2 carved out a durable niche in professional broadcasting that it holds to this day. The codec splits audio into 32 sub-bands via a polyphase filter bank, applies a psychoacoustic model to determine masking thresholds, then quantizes and Huffman-codes each sub-band accordingly. Typical broadcast deployments use 192-384 kbps for stereo, yielding transparent quality with lower encoder complexity and better error resilience than Layer III. These properties explain why DVB television, DAB digital radio, and the HDV camcorder standard all mandate or prefer MP2. Encoder latency is shorter too, an important trait for live broadcasting where lip-sync matters. Three advantages keep MP2 relevant decades after standardization: graceful degradation under transmission errors vital for over-the-air signals, minimal encoding delay that suits real-time broadcast chains, and entrenched regulatory acceptance across European and Asian broadcast frameworks.

Frequently Asked Questions

What is the benefit of converting 3GP to MP2?

MP2 remains mandatory in DVB broadcasting and DAB radio. Extracting MP2 from 3GP produces broadcast-compliant content for television and radio delivery.

How can I open MP2 files?

You can play MP2 with VLC, Winamp, and broadcast-oriented audio software used in radio and TV.

Will the entire audio track be extracted?

All audio from the 3GP source is captured in the MP2 output. The conversion preserves the full duration of the original soundtrack.

Is the conversion private and secure?

Your 3GP uploads are processed securely and removed right after conversion. Output files are purged within 24 hours to protect your privacy.

How long does 3GP to MP2 conversion take?

Processing time depends on file size and quality settings. Most clips convert to MP2 within a couple of minutes on our cloud servers.
