About formats

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.
Initial release: 1993
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

Why convert MP2 to SMP?

Converting MP2 to SMP adapts broadcast audio for legacy hardware, retro computing setups, or specialized vintage applications.

What programs can open SMP?

SMP is supported by Turtle Beach SampleVision editor and SoX for conversion.

Is there quality loss converting to SMP?

SMP is a specialized format with its own encoding constraints. Quality depends on SMP capabilities and the settings you choose.

How many MP2 files can I convert at a time?

Upload and convert multiple MP2 files to SMP simultaneously — the batch feature handles them all at once without repeating steps.

Are my conversions secure?

All uploads happen over encrypted connections. Your MP2 is deleted after conversion, and SMP results are cleared within 24 hours.

Does this work on mobile devices?

Yes. The converter is fully browser-based and works on smartphones and tablets — no app download required for MP2 to SMP conversion.
