Note 2: The impulse response samples are loaded in one of two ways: After importing, the “Design sample rate” can be changed to the desired rate for the FIR filter design. Note 1: FIR Designer & Creator use the “Design sample rate” value at the moment of importing. ColumnsĬolumn 2 : Impulse response samples (-1.0 to 1.0)Ĭolumn 4 (optional) : Coherence (0.0 to 1.0) Optional comment lines, before the data, can begin with “#” or “/*” (without the quotes) and are ignored. The decimal mark should be a “.” (dot, full-stop or period) and not a “,” (comma). Values should be separated by a ” ” (space) or “,” (comma). If the file contains 10 or more columns, the 1st line is assumed to contain impulse response samples.If the file contains 3 to 9 columns, the columns are assumed to start with frequency, magnitude, phase and optionally coherence.If the file contains only 1 or 2 columns of numbers, the file is assumed to contain impulse response samples.The following checks are run when importing text files. SMAART is a registered trademark of Rational Acoustics LLC, Connecticut, USA. The complex spectrum is loaded as frequency (Hz), magnitude (dB) and phase (degrees). SMAART transfer function files contain various data elements including the complex spectrum. The magnitude spectrum is loaded as frequency (Hz) and magnitude (dB) and the phase is set to 0 (degrees). SMAART spectrum files – both single channel and average – contain a magnitude only spectrum. Then any selected measurement can be transferred with one-click to FIR Designer’s ‘Import’ tab for use in FIR Designer’s workflow. A snapshot of a measurement, live streaming from SMAART, can taken and stored locally in a ‘grabbed’ measurement list.
SMAART’s signal generator on/off and measurement magnitude & phase banding or smoothing can all be controlled remotely. With SMAART open locally or on any networked computer, the ‘SMAART Control’ dialog can live-stream any available SMAART Spectrum or Transfer Function measurement.
SMAART Control enables loudspeaker measurements in Rational Acoustic’sSMAART software to be controlled by FIR Designer, captured in real-time & seamlessly integrated into the FIR Designer workflow for use in filter & preset creation. SMAART®įIR Designer and FIR Designer M have SMAART Control. The imported measurements & target responses are stored in their native form and sample-rate converted to the “Design sample rate” as necessary. Measurements in any file format can be averaged within FIR Designer and FIR Designer M (or by using the stand-alone Averager tool) an unlimited number or imported measurements can be combined into a single measurement for use in filter design (subject to computer memory limits).Ī NOTE ABOUT MEASUREMENT RESAMPLING The “Design sample rate” parameter doesn’t need to match the sample rate of any imported measurements & target responses. This page provides file formats & loading instructions for the following brands as well as more generic file formats (Wave, FRD, Text & CSV). Files can be in the form of impulse response sample vectors or transfer functions (freq/mag/phase/coherence). Smaart v8 offers new ways to manage your data and your measurement environment, new multi-window capability, a new tab-based interface, added functionality for use on tablets and touch screen computers, computer-to-computer API capability and much, much more.Įclipse Audio software tools can import loudspeaker measurements in a variety of text based and binary file formats. Loudspeaker Measurement Import: Supported File Formats As stated earlier, quoting Smaart v8's manual, coherence detects if the measurement signal is contaminated by environmental noise or reverberation, i.e. B) 'Environmental noise causing measurement signal contamination'. Are common according to the Smaart v8 User Guide. Easier, More Intuitive Measurement Configuration. Smaart v8 offers new ways to manage your data and your measurement environment, new multi-window capability, a new tab-based interface, added functionality for use on tablets and touch screen computers, computer-to-computer API capability and much, much more.
