About format

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.
Initial release: 1990

Frequently Asked Questions

Why convert SMP to standard audio formats?

SMP is a sample-based format with minimal modern support. Converting to MP3 or WAV ensures your audio works on every current device and media player.

What opens SMP recordings?

SoX and some vintage sampler editors handle SMP. For day-to-day use, converting to a widely supported format is the recommended path.

Is there a cost for converting SMP?

No — free conversion is available on convertio.co. Premium subscriptions unlock higher file size limits and priority processing.

Can I queue multiple SMP conversions?

Yes, upload several SMP recordings at once, assign output formats, and convert them all in a single batch operation.

How fast does SMP conversion run?

Audio conversions typically complete in seconds. Server-side processing ensures consistent speed regardless of your local device performance.
