MCRS (Multi-Channel Sound Recording System)

Multichannel recording

A robust and stable logger engine allows you to record up to 32 channels simultaneously on a single computer. You can use different types of audio interfaces, from built-in codecs to external multi-channel USB interfaces, to achieve the required number of channels. Note that by switching from stereo to mono, you can double the number of channels with the same hardware. Each sound card runs in a separate thread, which increases the stability of the program as a whole.

ASIO and WDM support

The audio logger is available in two versions, WDM and ASIO. The first option is good for a few cheap sound cards that only support stereo recording. Multi-channel audio interfaces usually do not allow to use all the features with WDM drivers, so especially for them, we created the ASIO version.

Flexible channel settings

You can set a different operating mode for each of the recording channels - manual or automatic with voice activation. The voice-activated mode eliminates 'dead air', which significantly reduces disk space usage. You can select a separate folder to store audio recordings for each channel. Regardless, the location of all timestamped recordings is always stored in the database.

Audio recordings management

For easy management of recordings, they are automatically divided into individual segments. You can change the duration of the segments in the program settings and also synchronize them with the time of day to make them more convenient to work with. When a recording is split into segments, it can happen that the recording stops in the middle of a word. To avoid such problems, you can set an overlap time between two consecutive recordings.

Recording scheduler

The scheduler allows you to set individual time slots for each channel. The number of time slots for each channel is unlimited. The channels remain in their original mode - they operate either in manual mode or with voice activation.

Recording browser

You can use a single browser with playback, sorting and search capabilities to access your audio recordings. In addition to this, you can also install a free audio-editing extension.

Volume Control

In most cases, you will use the AGC to adjust the recording level in real time. Although convenient, it does not always give acceptable results and is not available for all audio interfaces. Alternatively, you can use the normalization function to simply equalize the volume between channels. Since the final volume level is already known at this point, no additional scanning is required.

Output formats

The most common audio formats used to store recordings are MP3 and WAV. MP3 is well suited for voice recordings where high quality is not required. WAV, on the other hand, provides lossless compression. Based on this, you can choose between audio quality and audio file size. Never increase the sampling rate unless it is really necessary. Bear in mind that higher recording quality increases data flow. As a consequence, this increases the speed requirements for the hard drives.

Security

Unauthorized actions can lead to the loss of important information. To prevent tampering, you have the option of setting a password to change program settings, view audio recordings or stop recording. All events that occur while the program is running are recorded in logs and can be viewed at any time.

Typical Applications

• Capturing and archiving audio streams from virtually any source (FM, AM, DVB, DAB, HDRadio, internet, satellite etc.)
• Phone line logging
• Radio stations logging
• Checking your own program and to monitor competition
• Radio communications recording
• Court room recording
• Record radio traffic in police/fire/ems department
• Can be used as a "skimmer" to log audio from an microphone

System Requirements

• Microsoft Windows 11/10/8/7
• Microsoft Internet Explorer 6 or higher
• DirectX 9.0 or better
• Pentium III processor or faster
• 8 MB RAM or more.
• To record 2 mono channels - buy a simple Y cable from your local electronics to wire 2 mono sockets to a stereo plug. Then using Channel Properties assign one channel to "left mono" and the other to "right mono".
• Multichannel Recording required multiple standard sound cards or multichannel sound cards. Depending on hardware resources you can install up to 4 sound cards in one PC. (ie. a total of 8 inputs).
• Multichannel sound cards that have been tested including the M-Audio Delta 44, M-Audio Delta 1010, ESI Maya 44, Antex LX-44, RME FireFace 400, TASCAM US 4x4, Dialogic 12-channels interface cards.
• USB sound devices. USB devices usually can be used with a hub to connect many devices to one PC. Most modern USB sound devices let you do this.
• Microphones or telephone adapters
