Extract text from Spectroscopy and MIDI files (SMF)
To convert SMF MIDI files to another format, you need PerkinElmer Spectrum or other Data software.
To convert other file formats to the "Instrument Data & Audio Sequences" file type, you need software like PerkinElmer Spectrum or a similar tool.
The .SMF extension is notoriously fragmented, most frequently operating as either Spectroscopy spectrum data exported from PerkinElmer lab equipment or as a Standard MIDI File for digital music sequencing. Less commonly, it serves as an ODF Math formula file in Apache OpenOffice, a CAD container file, or a 3D model asset in gaming engines like CryEngine.
Because so many different developers chose the .SMF extension, these files present severe compatibility challenges. A spectroscopy dataset requires expensive, proprietary software like PerkinElmer Spectrum or specialized third-party tools like Spectragryph to read. Meanwhile, standard MIDI files only contain note instructions, not actual audio waves, meaning they cannot be played natively by modern web browsers and will sound drastically different depending on the device's built-in sound bank.
To ensure your data is actually usable, conversion is almost always required. For spectroscopy data, convert .SMF to CSV or TXT to enable plotting in Excel or Python. For audio, converting MIDI-based .SMF files to MP3 or WAV will bake the instrument sounds into a universal, web-ready audio track. Just drag and drop your file here to analyze and convert it - free, online, and without installing software.
Use Convert.Guru to open and convert your SMF file.
Users also converted MID, MP3, SMFF, MIDI, MMF, WAV, TXT, SFM, SWF, MP4, SF2, RCD and STY files.
If you want to convert SMF file to MIDI, STL, MP3, MMF, WAV, AAC, FLAC, OGG, WMA, M4A, AIFF or OPUS, you can use PerkinElmer Spectrum or similar software from the "Spectroscopy Data or Audio" category. In the File menu, look for Save As… or Export….
To convert MIDI, AAC, TTA, AU, WV, DTS, MID, FLAC, RA, MP3, PCM or WAV files to SMF, try PerkinElmer Spectrum or another comparable tool in the "Spectroscopy Data or Audio" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SMF converter.
