With more than 15 individual metering tools, SpectraFoo gives you all of the information you need to analyze and prepare your audio, for production, performance, mastering, or broadcast.SpectraFoo Complete was created for live sound engineers and mixing engineers. Including tools to measure your acoustic environment or verify the behavior of your external digital devices, SpectraFoo Complete provides the following additions to SpectraFoo: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, or alternatively striping signal into a capture or into an AIFF or 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 and White noise generation • Burst Generation• FFT synchronized sine generation• Direct generation to audio I/O, captures and filesTransfer Function Measurement System: For live sound, equipment testing, or any application where you need to analyze the characteristics of acoustical and electrical audio systems, SpectraFoo Complete's built in transfer function display shows you the relative power and phase response between the left and right channels. Using Metric Halo's Music Based Measurementô, the source signal is the input to some audio processing arrangement and 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 and the transfer function display shows the differences in amplitude and phase between the source and 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 and 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 and 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 and 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 and compensate for the measurement delay, time-aligning the two signals.   Capture and Static Analysis system: Allows you to record directly into SpectraFoo's RAM based capture system• Provides loop playback• Allows you to open sound files for detailed analysisRecord selections of audio into the computer’s RAM and perform incredibly detailed non-realtime analysis. All captures are referenced to the timecode of the source material. Captures may be initiated manually or can be triggered automatically, either with a level-based trigger or a time-based trigger. All recording is controlled and initiated by three basic capture modes that you may use: 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. 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 and 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 and 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, and test and design DSP algorithms with this comprehensive readout.The Bit Matrix Meter is designed to work with 16-bit delivery media and only utilizes the top 16 bits of the samples in the signal. The meter takes the 16-bit samples and divides them into two groups: the most significant byte (MSB) which is the top 8 bits, and the least significant byte (LSB) which is the bottom 8 bits. For each sample these groups are then converted to horizontal (MSB) and vertical (LSB) offsets into a 256x256 pixel matrix.Bit Matrix Meter (Accumulation Snapshot): Switch the Bit Matrix Meter into Accumulation Mode and display the aggregate utilization of the code space. The accumulation mode does not erase the bit matrix with each new time-slice and 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 or so is pretty sparse. This indicates that we could compress this signal with a pretty hard ratio and a 3dB threshold and introduce very little distortion.

Pure Analyzer System – The Next Generation RTA (Real Time Analyzer) System The Flux:: Pure Analyzer System is a network-driven modular RTA-system providing an extensive range of analyzer options for any imaginable audio analysis and measurement applications. For maximum flexibility and efficiency, Pure Analyzer presents the option to separate the signal acquisition from the analysis utilizing a Sample grabber plug-in, and in addition to the Sample grabber plug-in, Pure Analyzer also provide I/O support for ASIO and Core Audio.   Sample Grabber Sample grabber is a standard DAW plug-in available in all common formats (VST, AU, RTAS and TDM) that acquires the source and response signals and sends the signal through the network using the ZeroConf/Apple Bonjour protocol. You can insert as many instances of Sample grabber plug-ins as required, on the same DAW, different DAWs, and even different computers altogether, and the Sample grabber also support surround configurations. The network configuration setup for the Pure Analyzer System is entirely automatic and transparent to the user. The audio transport requires approximately 1.4Mbps for each channel at a sample rate of 44.1kHz, so a properly configured standard Ethernet 100Mbps network should be more than sufficient to handle most cases. A 5.1 configuration at 96kHz demands a little less than 20Mbps. Naturally these requirements do not apply when using both Sample grabber and analyzer on the same hardware.   Pure Analyzer Essential The foundation of the Pure Analyzer System is a standalone application, Pure Analyzer Essential, which can be extended with modules for Live, Metering/Loudness and Surround analysis, performing the graphic analysis rendering using a GPU-efficient 2D/3D graphic engine. The engine is based on the OpenGL standard optimizing the audio-to-visual experience utilizing the GPU on the built in graphics card. The Pure Analyzer Essential application receives the sample feeds from the Sample grabber and analyzes them in real time. The Pure Analyzer provides the option to receive data from several different Sample grabber plug-ins on the network, and analyze the received data in parallel by selecting the actual corresponding Sample grabber to be the current source for the analysis with a simple button click. In addition to this, the input streams from the physical ASIO/Core Audio I/O can also be selected as the current source for the analysis in the same simplistic fashion.   Main Features   Basic metering Peak meter Basic RMS meter Fully customizable scale and ballistics Phase meter Weighting filters ITU-R BS.1770-2 (K-weighting) ANSI A ANSI B ANSI C Real-time spectrum analyzer Standard FFT or unique Flux:: Spectrum representation Block size up to 64 K Configurable analysis window Rectangular Barlett Blackman Hamming Hann Amplitude or power frequency scaling Time-averaging Continuously running Fill/freeze refresh/display cycle User-adjustable length up to 200 frames Max (accumulated) or running mode Display channels’ sum or a number of channels, user-selected User-adjustable fixed range or automatic range Simultaneous display of: Raw, full-resolution curve Smoothed curve with user-adjustable detail setting Peak curve Independently adjustable curve ballistics Peak tracking with user definable frequency range and several display variations Keyboard and mouse frequency-axis zoom Fully-customizable curve visual options Spectrogram Display Color modes Power grading Frequency grading Range Min Range Max Vector Scope Internal processing up to 768 KHz Auto-scaling Fully adjustable display Blending Fading Blurring Scaling Several color modes Static color Power grading Dynamic grading Power + Dynamic grading Nebula stereo (Front projection only) Unique spectrum over space scope, providing real-time visualization of the the audio content in the stereo space-frequency domain.
