| Sinc Audio RCS Facts | | Sinc Audio Room Correction System
Sinc Audio RCS is a software package for use on a PC. It includes all the functionality necessary from measurement of the combined room/loudspeaker response to room-correction playback. The software package consists of these applications:
| RC Make |
Measure the combined room/loudspeaker response. Design target magnitude responses. Create and evaluate correction filters. |
| RCDVD |
Media player supporting: DVD, CD-Audio, external source and audio files. |
The room-correction playback software is highly efficient, and utilise the new multimedia instruction sets available on current processors. An advanced multirate filter-structure is used, making possible high-resolution correction. Supported sampling rates up to 192KHz.
The software combined with hardware makes up a very flexible system. Subsystems can easily be updated with later technology advancements (or heavier wallet) opposed to integrated systems.
System Requirements:
| Hardware |
Intel architecture processor. Instruction set of Intel Pentium of better. |
| OS |
Windows XP. Windows Vista. Windows 7. Both 32-bit and 64-bit support. |
Note: An "Intel architecture processor" could be an AMD processor.
For real-time operation of room correction playback, the speed of your PC should be comparable to that of an Intel Pentium III/500MHz for 44.1KHz/ 48KHz stereo playback. These are not absolute figures. The sound will break up if your system isn’t fast enough. Try it.
Soundcard:
Your soundcard must support full duplex mode. I.e. it must be able to record and playback at the same time. Most modern soundcards do support full duplex mode. Other requirements:
| Samplerate |
48000Hz |
| Bits per sample |
24bits or better for playback. 16bits or better for measurements. |
Because the signal must be downscaled during room-correction playback to avoid saturation, 24bits per sample is needed during playback. The software supports up to 32bits per sample.
Microphone:
To measure the combined loudspeaker/room response, an omnidirectional microphone must be used. An omnidirectional microphone has ideally equal sensitivity to sound from all directions. This version of the software does not compensate for the impact of the microphone. Normally the deficiencies of the microphone will be much less than those of the combined loudspeaker/room response.
You might need:
If the microphone signal level is not sufficient to drive your soundcard, you need a microphone amplifier.
If you are using a soundcard without analog input/output you need an external AD/DA-converter. |
