SMP to PCM Converter
Processing entirely on your device — large files may take a moment.
Convert any audio to raw PCM for DSP pipelines, or wrap a PCM dump into WAV/MP3 to make it playable. If your files are still in SMP format, this page is the shortcut: SMP is the Turtle Beach sample format — raw 8/16-bit PCM dumps used by early PC sound-card sample editors.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the SMP format
SMP is the Turtle Beach sample format — raw 8/16-bit PCM dumps used by early PC sound-card sample editors.
ffmpeg decodes it natively inside your browser — the audio track is re-encoded to your chosen format with nothing ever uploaded.
+Strengths
- ✓Decoded natively by ffmpeg
- ✓Runs entirely in your browser
- ✓Free, private, no watermarks
!Limitations
- −Legacy niche format
- −Modern tools rarely open it
- −Keep the original for archival round-trips
About the PCM format
Raw PCM is audio at its most naked: 16-bit little-endian samples, no header, no metadata, no sample-rate label — just the waveform bytes. It is the lowest common denominator every DSP pipeline, telephony stack and embedded system speaks, which is why exports and lab tools keep asking for it.
Because the file carries no sample-rate information, consumers must agree on the rate out of band (8000 Hz telephony and 48000 Hz video are the common conventions). Wrapping PCM into WAV adds the missing header and makes the bytes playable anywhere.
+Strengths
- ✓Zero overhead — pure sample data
- ✓Universally understood by DSP tools
- ✓Bit-exact lossless representation
!Limitations
- −No header: sample rate must be known out of band
- −Unplayable directly in most apps
Why convert SMP to PCM?
Think of it as moving your file to the container that fits the job. Legacy niche format PCM works differently: Zero overhead — pure sample data If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this SMP to PCM converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for SMP to PCM?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Will converting SMP to PCM reduce audio quality?
If PCM is lossless, the output contains everything the SMP file contains — no further loss is added. If PCM is lossy, one recompression pass is unavoidable; the quality slider controls how much. Loss that already happened in the source file can never be undone by converting.
Can I convert a whole folder of SMP files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
