Convert SMP Files Free

What is SMP (SampleVision) format?

SMP is sample format from Turtle Beach SampleVision - a DOS-based sample editing software from early 1990s. SampleVision was professional tool for editing sampler instruments before software samplers existed. Musicians used it to create and edit samples for hardware samplers (Akai, E-mu, Roland, Ensoniq). SMP files stored individual audio samples with loop points and metadata for loading into hardware samplers.

Historical context: Pre-2000, music production relied on hardware samplers - rack units or keyboard workstations storing sampled instruments. Creating custom samples required sample editors. SampleVision was DOS standard for this work, competing with AKAI's software and E-mu's tools. SMP format was native SampleVision storage - producers accumulated huge SMP libraries of drum hits, instrument recordings, and sound effects.

Should I convert SMP to WAV or keep original format?

Strong reasons to convert SMP samples:

Dead Software

SampleVision is 1990s DOS program. Doesn't run on Windows 10/11. Conversion is only practical access.

Modern Samplers

Kontakt, HALion, Ableton Sampler use WAV samples. Convert SMP to use in current music production tools.

Metadata Loss Risk

SMP loop points and metadata might not transfer. Export to WAV with manual loop documentation.

Archive Accessibility

Sample libraries in SMP are inaccessible long-term. WAV ensures future usability as tools evolve.

Convert SMP to WAV immediately. Sample content has value; format doesn't. WAV works in all modern samplers and DAWs.

What metadata do SMP files contain?

Loop points: SMP files store sample loop start/end markers essential for sustained instrument sounds (strings, organs, pads). Hardware samplers need loops to hold notes indefinitely. Loop points are critical metadata - without them, samples play once and stop. Converting SMP to WAV loses loops unless converter preserves them in WAV metadata.

Sample rate and bit depth: SMP metadata includes audio specifications - typically 44.1kHz/16-bit (CD quality) for professional samples. Might be lower (22kHz, 8-bit) for budget samplers or older libraries. Knowing source specs helps verify conversion accuracy.

Original pitch information: Some SMP files include root note (C3, A4, etc.) indicating sample's original pitch. Hardware samplers use this for keyboard mapping. Converting to plain WAV loses this - you'd need to document pitch separately or use sampler-specific formats (Kontakt, SFZ) that preserve instrument mapping.

Can modern samplers read SMP files directly?

Generally no: Kontakt, HALion, UVI Falcon, Ableton Sampler, Logic EXS24 - none natively import SMP. Format is too obscure and obsolete. Modern samplers expect WAV, AIFF, or proprietary formats (NKI, FXP). SMP support would require implementing 1990s DOS format reader - not worthwhile for manufacturers.

Why no support: SMP user base is tiny (vintage producers with old DOS libraries). Development cost of supporting niche format doesn't justify. Manufacturers assume users convert SMP to WAV rather than demanding direct support. Market reality: old formats die when software stops supporting them.

Workaround: Convert SMP to WAV, then load WAV into modern sampler. Manually recreate loop points using sampler's loop editor. Time-consuming but necessary. Modern sampler instruments are WAV-based; SMP conversion is preprocessing step before instrument creation.

What was Turtle Beach SampleVision used for?

Professional sample editing: Musicians and sound designers used SampleVision to prepare samples for hardware samplers. Edit waveforms (trim, normalize, fade), set loop points precisely, apply processing (EQ, filtering), organize multi-sample instruments. It was Pro Tools equivalent for sampler users - professional quality tool for serious production.

Sample library creation: Commercial sample developers (Time+Space, EastWest, Spectrasonics precursors) used SampleVision to create sample libraries for Akai, E-mu, Roland samplers. SMP files were working format before final conversion to sampler-specific formats. Many classic 1990s sample CDs were created with SampleVision workflow.

Audio extraction: SampleVision could extract samples from audio CDs, vinyl, or synthesizers. Before Recycle and modern sampling tools, SampleVision was primary method for capturing and editing samples. Hip-hop producers, electronic musicians, and film composers relied on it. SMP libraries represent 1990s production techniques and sound design aesthetics.

Why did SampleVision disappear?

DOS to Windows transition killed it: SampleVision was DOS software (16-bit). When Windows 95/98 arrived, 32-bit applications became standard. Turtle Beach never updated SampleVision for Windows. Software became incompatible with modern systems. Users migrated to Windows audio editors (Sound Forge, WaveLab, Cool Edit) that offered sample editing plus more features.

Software samplers emerged: Late 1990s/early 2000s brought software samplers (GigaStudio, Kontakt, HALion). These ran natively on computers, used WAV files directly, and integrated with DAWs. Hardware sampler workflow (edit in SampleVision, transfer to hardware via SCSI/MIDI) became obsolete. Software samplers eliminated need for specialized sample editors - edit WAV files in DAW, load into sampler plugin. SampleVision's niche vanished.

Turtle Beach focus changed: Turtle Beach shifted from professional audio tools to consumer sound cards and gaming headsets. SampleVision was abandoned as company pursued different markets. Without updates, format became obsolete. Lesson: proprietary formats die when companies change strategy. Open formats (WAV) survive corporate decisions.

What quality are SMP samples?

SMP audio specifications varied:

Professional Samples

44.1kHz/16-bit CD quality typical for professional SampleVision libraries. Studio-grade recordings.

Budget Samplers

22kHz/8-bit or 22kHz/12-bit for cheaper hardware samplers with limited memory. Lower fidelity.

Uncompressed Audio

SMP stores uncompressed PCM - no lossy compression. Converting to WAV preserves quality exactly.

Bit Depth Variations

Vintage samplers supported 8-bit, 12-bit, 16-bit. SMP accommodated various bit depths for different hardware.

Loop Quality

Professional SMP libraries had carefully edited loops - crossfades, zero-crossing edits. Quality loop craftsmanship.

SMP samples range from professional CD quality to lo-fi 8-bit. Conversion to WAV maintains source quality without degradation.

Can I extract SMP files from old sample CDs?

If CD contains SMP files: Mount CD, copy SMP files to hard drive, then convert. Many 1990s sample CDs included SMP versions alongside Akai/E-mu formats. Check CD contents - might have SMP directory. Ripping is straightforward file copying.

If CD has audio tracks: Use audio CD ripper (Exact Audio Copy, dBpoweramp, iTunes) to extract tracks as WAV. CD audio isn't SMP format - it's standard Red Book audio. You get WAV files directly, no SMP conversion needed. Many sample CDs were audio CDs, not data CDs with SMP files.

Sampler-specific formats: Some CDs have Akai S1000/S3000, E-mu, or Ensoniq formats - not SMP. Each hardware sampler had proprietary format. If CD says "Akai format", you need Akai conversion tools (Extreme Sample Converter, Translator), not SMP tools. Format identification crucial for choosing correct conversion method.

What's the difference between SMP and sampler formats like Akai?

Sample format distinctions:

SMP (SampleVision)

Computer-based editing format. DOS software native format. Used for sample preparation before transfer to hardware.

Akai (S1000/S3000)

Hardware sampler disk format. Stored on floppy/SCSI/CD for loading into Akai hardware. Industry standard sampler.

E-mu (EOS/ESI)

E-mu Systems sampler format. Different structure from Akai. Used in E-mu Emulator and ESI samplers.

Roland (S-series)

Roland sampler format (S-50, S-760). Yet another proprietary structure. Hardware-specific.

All Convert to WAV

Modern workflow: extract audio from any vintage format, convert to WAV, use in software samplers. Format irrelevant once converted.

Are SMP sample libraries valuable to preserve?

Absolutely - audio content has lasting value. Even if SMP format is dead, the actual samples (drum hits, instrument recordings, synth sounds, sound effects) are useful. 1990s sample libraries captured specific equipment, production techniques, and sonic aesthetics. These are historical audio artifacts and practical production resources.

Cultural significance: Sample-based music (hip-hop, electronic, film scoring) built on libraries like these. SMP archives document production tools and sounds from specific era. Preserving means converting to accessible formats (WAV), documenting metadata (library name, source, date), and archiving properly. Audio archaeology preserves sonic culture.

Practical use: Converted SMP samples work in modern production. Vintage drum machines, analog synth samples, classic orchestral recordings - all still musically useful. Lo-fi aesthetic is trendy again; vintage samples are creative resources. Convert SMP libraries to WAV, catalog them, use in current projects. Format is dead but content lives on.

How do I preserve loop points when converting SMP?

If converter supports it: Some specialized tools extract SMP loop markers and embed them in WAV metadata (BWF/iXML chunks, RIFF INFO). This is ideal - preserves loops in standard format. However, most tools ignore loops or can't write them to WAV properly. Verify converter loop handling before batch processing.

Manual documentation: Export SMP to WAV, note loop points separately (spreadsheet, text file). When loading WAV into modern sampler, manually set loops using documented points. Tedious but reliable. For valuable sample libraries, this effort preserves original editing work.

Modern sampler formats: Consider converting SMP not just to WAV but to modern sampler format (SFZ, Kontakt, HALion). These formats store loop points, velocity layers, keyboard mapping. More work than simple WAV conversion but creates immediately usable sampler instruments. Preserves loop information in useful way.

Can DOSBox run SampleVision reliably?

Yes, with caveats: DOSBox emulates DOS environment well enough to run SampleVision. You can load SMP files, view waveforms, edit, and export. However, audio hardware emulation in DOSBox is limited - real-time playback might be choppy. For conversion workflow (load, export, don't edit), DOSBox works fine. Sound output quality doesn't matter if you're just extracting to WAV.

Setup complexity: Need to configure DOSBox (mount drives, allocate memory), locate SampleVision software (abandonware archives), understand DOS commands (DIR, CD, file paths). Not difficult for technical users but barrier for casual users. Once set up, batch conversion is possible through DOSBox scripting or manual processing.

Alternative: 86Box or PCem provide more accurate DOS hardware emulation if DOSBox fails. These emulators replicate entire PC hardware, ensuring better compatibility with temperamental DOS software. Overkill for SMP conversion but option if DOSBox doesn't work. For most users, DOSBox is sufficient.

What other sample formats should I know about?

Common vintage formats: Akai (most popular hardware sampler format), E-mu (.e3x, .e4x), GigaStudio (.gig), SoundFont (.sf2), Kurzweil (.krz), Roland (.s7x), Ensoniq (.efe). Each hardware/software sampler created proprietary format. Sample format fragmentation was nightmare - same audio content in dozen incompatible formats.

Modern standards: WAV/AIFF (universal audio files), SFZ (open sampler instrument format), Kontakt (.nki - industry standard), HALion (.vstsound), UVI (.ufs). Better than 1990s chaos but still some proprietary formats. SFZ is best open standard - text-based format describing how WAV files map to keyboard, with loops, velocity layers, etc.

Conversion tools: Extreme Sample Converter, Awave Studio, CDXtract, Translator - commercial tools supporting multiple vintage formats. Expensive but necessary for professional sample library conversion. For casual users, format-specific free tools exist (Akai converters, SoundFont editors). Sample format conversion is specialized skill in audio preservation field.

Should I keep SMP originals after converting to WAV?

For archival purposes, yes: SMP files are original artifacts. Even if converted WAV is practical format, SMP preserves original loop points, metadata, and format authenticity. Disk storage is cheap - keeping both formats ensures complete preservation. Future tools might extract SMP metadata better than current tools.

Document everything: Note source of SMP files (library name, CD/disk, date acquired), conversion tool used, any metadata loss, loop point locations. SMP files without context lose value. Catalog makes preserved samples useful for research or production. Good archival practice whether format is dead or alive.

Practical vs archival: For personal use (your own samples), WAV conversion alone probably sufficient. For historical sample libraries (commercial releases, professional collections), preserve SMP + WAV + documentation. Archival significance determines preservation depth. Balance preservation idealism with practical storage/effort constraints.
