Metric Halo’s SpectraFoo provides all of the analysis and measurement tools that today’s digital projects demand. Designed for both live sound engineers and studio mixers and recordists, the power that Foo provides includes standards-based level metering, high-speed, high-resolution spectral analysis, the unique Phase Torch, correlation metering, triggerable waveform display, power balancing and a variety of power, envelope and spectral histories and phase analysis. SpectraFoo is absolutely essential for broadcast production, critical mixing and mastering. |

| SpectraFoo :: Powerful Metering & Metrics, StandardThe SpectraFoo Standard edition includes basic, sample-accurate metering, triggerable waveform display, power balancing and phase analysis: • A three–in–one Digital Level Meter simultaneously displays Peak, RMS, and VU levels. The Peak and RMS meters each have independent, resettable peak hold functions. Also includes a Peak and RMS Power History. • A Phase Scope provides a classic Lissajous X-Y display. • A Power Balance History compares the power balance between the input channels as a function of time. • A real-time, high resolution Spectrum Analyzer allows you to see musical structures, even at the highest tempos. • A real–time Spectragram provides spectral power analysis gives you a visual “sonic fingerprint.” • A Correlation Meter reduces the relative phase information between channels to a number between -1 and 1, resulting in an easy to read trend of imaging & mono compatibility. • A Correlation History readout provides you with a time history of the Correlation Meter for better interpretation of trends. • A Band Power History readout displays the history of the amount of power in a specified band of the spectrum, very effective for ferreting out resonances. • The revolutionary Phase Torch™ compares the phase difference between two channels as a function of frequency, independent of power and is great for setting azimuth, checking time alignment and mono compatibility as well as identifying frequency dependent phase and polarity problems. • An Envelope History tool is useful for identifying large level changes when the average level is high. • A Time Code Clock that locks to external SMPTE/EBU or MIDI time code sources or the computer’s internal clock or CD drive. • A full featured Triggering Oscilloscope gives you the wave shape characteristics of very low level signals. The oscilloscope includes trigger and hold with seven trigger modes. |

| SpectraFoo :: Powerful Metering & Metrics, CompleteSpectraFoo Complete builds on the Standard edition, providing engineers with all of the tools in SpectraFoo Standard plus, sample code metering tools, a 12 band signal generator, a recording, playback, looping & static analysis system, and a complete transfer function measurement system: • A Bit Range Meter displays the range of sample codes exercised in the assigned channel of each time slice, showing you the activity in each bit of the AES/EBU sample word and which bits are being exercised. • A Bitscope visually displays the state of all bits in all samples in a time slice. This allows you to easily see low level activity in your signal, “stuck” bits and DC offsets. • A Bit Matrix Meter pinpoint problems in your data stream, and helps you visually determine how the AES/EBU is being “filled.” • A high resolution, multi–tone, multi–noise, sweepable, burstable signal generator. The generator is runs either in real time or into a captured AIFF or SDII file. The precise numeric interface controls: 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 file capture • A full featured Transfer Function Measurement system that includes a Delay Detection feature to properly measure the power and phase of a system’s response relative to the source signal. • A Capture and Static Analysis system that allows you to record directly into SpectraFoo's RAM based capture system. This provides loop playback and affords the ability to open sound files later for detailed analysis. |
