Publisher's description of Sonic Beacon 1.1.0.5
|
Loudspeaker and electroacoustic test software
|
Sonic beacon is a PC-based test and measurement system for the testing of loudspeakers and other electro-acoustic products using commercially available Windows multimedia sound cards. Sonic beacon will perform Frequency and Phase Response, Harmonic and Intermodulation Distortion, Polarity, Impedance, Sensitivity and SPL as well as other FFT and Real Time Analysis tests, Sixteen bit sampling rates up to 192 kHz and FFT lengths up to 128K points are supported.
Sonic beacon contains six different virtual instruments that can be cascaded in order to form a process. An input signal emanating from a WAVE audio file, the Signal generator or a sound card may be passed serially from one module to another. Each module performs a process on this signal and alters its time or frequency domain representation. If the modules are coherently cascaded a sensible analysis can be done on the input signal. It also contains a unique calibration algorithm that allows for the compensation of input level, latency and frequency response errors in personal computer sound card electronics. These calibrations may be saved to a file and subsequently recalled and applied to any new process that uses the sound card.
Multiple process streams may be opened within the application and will execute simultaneously. Multiple instances of the application can also be opened. Data may be transferred to and from instances of the application, processes, text editors and spreadsheets using the Windows clipboard. Modules may be added or deleted at any point in a process stream and all existing instruments, in the process, will retain their current settings. Process streams may be saved to disk and all instruments will retain their current settings, size and location when recalled.
Any module with a display screen may be previewed or printed. Debugging options include Pause on Every Module and Pause On Every nth Record.

Key features for "Sonic Beacon 1.1.0.5"
The following virtual instrument modules are available :
• WAVE File Open Module: Opens a PCM file and converts it data to the internal FFT records required by the processing application.
• Signal Generator Module: Outputs a variety of wave shapes at frequencies from 0 Hz to one half the current sample rate.
• Arbitrary Filter Module: A digital filter with an arbitrary, programmable amplitude and phase response.
• Oscilloscope Module: An oscilloscope module that displays two channels of time domain data
• Spectrum Analyzer Module: A two channel Spectrum Analyzer module that can perform FFT’s, Cross Correlations and FHT’s Transforms on time domain data.
• DataLogger Module: A color keyed, persistent plotting engine that can display data in either the time or frequency domain.
• SoundIO Module: Records and plays audio signals on any PC sound card that is compatible with Windows multimedia services
• WAVE File Save Module: Converts digital signal data generated by a stream of process modules to RIFF and saves it to disk as a PCM Waveform audio file (.WAV). |
Requirements for Sonic Beacon 1.1.0.5:
Hardware requirements:
• Computer with Intel 32-bit x86-based microprocessor (such as the Pentium) or higher. This application requires at least a 400 MHz processor in order to play audio in real time. The more modules in a process stream the higher the performance of the processor must be in order to achieve real time throughput. Real time throughput is not required to measure the performance of audio components.
• 128 MB RAM, minimum! Performance of the application at large FFT sizes can be severely degraded if memory to disk swap files must be accessed.
• VGA monitor capable of displaying 256 colors.
• Hard Disk with 20MB of free space. Additional space is required to save audio and additional calibration files. A sound card calibration file for 32768 FFT size is 3.2 Mbytes.
• Windows compatible sound card: Sixteen bit duplex card is absolutely required for audio component measurements.
• Two Button Mouse. A central wheel is not required.
• CD-ROM is optional.
• Microsoft Windows XP Home, Windows XP Professional or Windows Vista Home Premium compatible Network adapter is optional.
Software requirements:
• Microsoft Windows XP Home, Windows XP Professional or Windows Vista Home Premium. Note that sonic beacon is not tested on Windows 1.01 - 3.1x, Windows for Workgroups, Windows 95, Windows 98, Windows NT, Windows 2000, Windows ME, Windows CE, Windows XP 64 Bit Edition 2003, Windows Server 2003, Windows XP Professional x64 Bit Edition, Windows Fundementals for Legacy PCs, Windows Vista 64 Bit, Windows Vista Ultimate, Windows Home Server, Windows Server 2008, Windows 7 (Vienna) or Windows Strata (Cloud).
• Duplex Sound Card drivers (supplied with Sound Card hardware). Duplex drivers are usually available on manufacturers web sites for older hardware. To check if your sound card is capable of duplex operation; open two instances of the operating systems Sound Recorder application. In the first load a wav file of at least 400 Kbytes (about 5 seconds of sound). Press the record button in the second Sound Recorder and then press the play button in the first. After about 5 seconds press the stop button in the second recorder. Reset its media position to 0.00 sec and press its play button. If the second recorder is playing what the first played originally then the hardware is duplex capable. If any error messages appear during the process you may have to obtain new hardware or obtain duplex drivers. Almost all sound cards manufactured after 1997 are duplex capable.
• Basic MMSYSTEM support is required. It is always included in any of the aforementioned operating systems. DirectX support is not required.
• Sonic beacon.exe is built with Microsoft Common Language Runtime Support disabled.
• ATL support is not required.
• Sonic beacon.exe dynamically links to Microsoft C Runtime Libraries. If the side by side assemblies are not available on the target these are accessed from the applications installation directory using manifests. The required manifest and its three accompanying dll’s are installed by the setup utility.
• Sonic beacon.exe dynamically links to Microsoft Foundation Class Libraries. If the side by side assemblies are not available on the target these are accessed from the applications installation directory using manifests. The required manifest and its four accompanying dll’s are installed by the setup utility.
Network requirements:
Networking is not a requirement for this application. If networking is necessary the client or server machines must be networked with one of the following products:
• Microsoft Windows XP Home.
• Windows XP Professional.
• Windows Vista Home Premium. |
