4 Elektronik GmbH MCD Audio Analyzer Description 1. General The audio analyzer is used for testing and calibration of analog and digital sound systems and can be used for converting analog audio signals into digital form and vice versa. Also the implementation of switching from an optical to electrical S / PDIF signals and vice versa is also possible. 2. Product Features 2.1. Software The audio analyzer is controlled with the MCD AudioAnalyzer.Net. For analysis of the audio signals in addition to the frequency and signal strength of various measurements, measurements of the distortion factor and the FFT spectrum is possible. Through the integrated signal generators, different waves and modulation forms are generated. The surface of the audio analyzer can be widely adapted and adjusted to varying applications. All functions of the audio analyzer can use different interfaces (COM server, DLL,.Net Assembly) are controlled by other Windows programs. The obtained values can also be integrated into a variety of programs. Special programming knowledge is not required.

21 Command 50 Recording audio data Command: Returns the currently applied audio data. The data is not transmitted as ASCII hex characters, rather than binary data. Hereby, two modes can be selected: - Simple: Up to samples can be read and then stop sampling. - Continuous: As above, but the sampling is not stopped, but the internal buffer further filled and with - The next request uses the audio data therefrom. If there is not enough data in the buffer, - The missing values collected and sent. It is always the requested number of samples is always supplied. At the end there may be an interruption displayed to the S / PDIF input, which is relevant only if the S / PDIF input is selected as the source. If the data is not fast enough collected, then the data that does not fit in the input buffer (2048 samples) are discarded, and displayed is an overflow. Please note: When you change from Continuous operation to simplicity the first request is still served from the input buffer. Data Parameter Description Valance Domain Infos $12 Trig.

22 Command 51 Selecting input source and sample rate Command: Assigns the signal sinks (analog output, analyzer (USB output) and S / PDIF output) to their source. The two S / PDIF outputs cannot simultaneously have the analog input and the generator as a source. Likewise, it is not possible to assign the analog output to the analog input, while the self test mode is active (because of feedback). Is for the analog output and the analyzer S / PDIF selected as the source, then both choose the same input. The last byte of data sets, with which sample rate the audio generator and the analog input work. The sample rate of the S / PDIF input is determined by the input signal. The sample rates of the signal sinks (analog output, S / PDIF output and analyzer) automatically have the sample rate of the respective designated source.

23 Command 53 Selecting Analog areas Selects the measuring ranges of the analog input and the maximum signal level of the analog output left and right respectively. If the ADC calibration is activated, the offset of the input signal is measured and removed directly at the ADW with a digital high pass filter. The time required for this is dependent on the sample rate of the ADCs (0.52 s at 192 khz to 2.27 s at 44.1 khz). To find the correct measuring range or when the input range is not changed may be omitted due to time constraints on the balance. If the measuring range is changed, the balancing should then be performed at least once before the measuring.

25 Command 61 Audio data output Defines audio data of the generated audio signal or the audio stream. In generator mode, the length and the contents of the ring buffer is determined, in streaming mode, the transferred data is appended to the still contained buffer. To begin with the generator mode, this should be switched off and switched to the generator mode of operation (command 60, data 00). After transferring the data, it can be started (command 60, data 01). Before the start of the streaming operation, should also be selected and only in the generator mode. After transmission of the first data packet is then inserted into the streaming mode and is turned on (instruction 60, data 03). If all supplied values during the stream cannot be written into the buffer, since it is partially full, the extra values are discarded and must be sent again. This is necessary so that the USB interface isn t block by data in the queue. The number of the accepted values is returned in the response.
