One tool many uses.SpectraFoo Complete FeaturesSpectraFoo has been designed to provide all of the tools you need for a powerful suite of digital meters with all of the resolution of hardware meters at a fraction of the price. With more than 15 individual metering tools SpectraFoo gives you all of the information you need to analyze   prepare your audio for production performance mastering   broadcast.SpectraFoo Complete was created for live sound engineers   mixing engineers. Including tools to measure your acoustic environment   verify the behavior of your external digital devices SpectraFoo Complete provides all of the features included in Metric Halos SpectraFoo Standard PLUS the following:Full featured world-class signal generator:SpectraFoo Complete has a high-resolution multi-tone multi-noise sweepable burstable signal generator. The generator is capable of running in real-time   alternatively striping signal into a capture   into an AIFF   SDII file. The interface to the signal generator is numerical which makes it very precise�� Provides high resolution 24-bit distortion free signal generation�� Up to 9 simultaneous sine sweeps�� Pink   White noise generation�� Burst Generation�� FFT synchronized sine generation�� Direct generation to audio I/O captures   filesTransfer Function Measurement System: For live sound equipment testing   any application where you need to analyze the characteristics of acoustical   electrical audio systems SpectraFoo Completes built in transfer function display shows you the relative power   phase response between the left   right channels. Using Metric Halos Music Based Measurementô the source signal is the input to some audio processing arrangement   the response signal is the measured output of the system making music your “test tone”. SpectraFoo uses the source signal as a point of reference   the transfer function display shows the differences in amplitude   phase between the source   response as function of frequency.This allows you to measure the properties of audio processing systems including systems that contain acoustic elements. You can determine the amplitude   phase response of an equalizer in the presence of musical signal as easily as measuring the sound coloration of an acoustic space.SpectraFoo provides a Delay Detection Feature to properly measure the power   phase of the response signal relative to the source signal as the source signal must be delayed to time-align it with the response signal. The delay finder records a segment of both signals   computes the correlation of the signals with each other. By moving the cursor to the largest correlation of the two signals you set the system delay   compensate for the measurement delay time-aligning the two signals.Capture   Static Analysis system: Allows you to record directly into SpectraFoos RAM based capture system�� Provides loop playback�� Allows you to open sound files for detailed analysisRecord selections of audio into the computer’s RAM   perform incredibly detailed non-realtime analysis. All captures are referenced to the timecode of the source material. Captures may be initiated manually   can be triggered automatically either with a level-based trigger   a time-based trigger. All recording is controlled   initiated by three basic capture modes that you may use:1. ManualUse manual mode to record on the fly. Click the record button to start recording   click it again to stop recording.2. Timecode-based auto-punchUse timecode-based auto-punch to record a segment of audio that starts at a particular time   ends at another time. This is like the auto- punch feature of many tape decks. Simply type the start   end times into the punch in   punch out fields   click the Record button. SpectraFoo will arm its auto-punch mechanism   wait until the timecode clock matches the punch-in time. It will then record until the timecode clock matches the punch-out time   automatically stop.3. Level-based auto-punch.Use level-based auto-punch to start   stop recording based on the volume of the audio being monitored.This is great for capturing individual drum beats   for capturing entire songs. A specific example of the usefulness of level-based captures is when you are trying to determine the optimal placement of microphones on a drum kit. When coupled with the Auto Arm feature level-based punches can be used to capture individual drum beats in a hands-free way allowing you to devote your attention to placing the mic while still benefiting from SpectraFoo’s analysis.When Data Slicing is enabled the realtime instruments display the data which lies underneath the current position of the cursor. If you drag the cursor around in the overview window the realtime instruments will continuously update to reflect the current cursor position. If you replay the capture the realtime rack will continuously update in sync with the playback.Code-Level Metering:Three different kinds of bit meters for monitoring the low level audio bitstreams:- Bit Range Meter: Displays the range of sample codes exercised in the assigned channel of each time slice. It shows the activity in each bit of the sample word   shows you which bits are being exercised.- Bit Scope: Displays a list of the codes of all of the samples in the time slice. This allows you to see low-level activity in the signal stuck bits DC offsets   the like.  Each time the display is updated all of the sample in the time slice are shown. The number of samples in the time slice are determined by the I/O hardware’s buffer size. The samples are displayed starting with the first sample in the time-slice in the upper left hand corner of the instrument. Each successive sample is place under the previous one until the bottom of the column is reached. The next sample is placed at the top of the next column.- Bit Matrix Meter (Instantaneous Snapshot):Pinpoint problems with processing algorithms in your data stream   test   design DSP algorithms with this comprehensive readout.  The Bit Matrix Meter is designed to work with 16-bit delivery media   only utilizes the top 16 bits of the samples in the signal. The meter takes the 16-bit samples   divides them into two groups: the most significant byte (MSB) which is the top 8 bits   the least significant byte (LSB) which is the bottom 8 bits. For each sample these groups are then converted to horizontal (MSB)   vertical (LSB) offsets into a 256x256 pixel matrix.Bit Matrix Meter (Accumulation Snapshot): Switch the Bit Matrix Meter into Accumulation Mode   display the aggregate utilization of the code space. The accumulation mode does not erase the bit matrix with each new time-slice   this accumulates a picture of all of the sample code that have been exercised by the signal. This snapshot shows us that while most of the codespace is exercised by the signal the top 3dB   so is pretty sparse. This indicates that we could compress this signal with a pretty hard ratio   a 3dB threshold   introduce very little distortion.
