In DepthCode-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 and shows you which bits are being exercised.
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.
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.
Full featured world-class signal generator.
SpectraFoo Complete now 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 files
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 Measurement™, 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.
Plug-in, Standalone, and Plug-in driven Standalone versions of the software
are all included in the same package, allowing you to work as the situation warrants.
Supported environments are TDM (MIX, TDM III and even nuBus),
RTAS and MAS.
