• RAM 128 MB
• 10 MB free disk space

Test of Sloud MRM Audio Fingerprinting

• Start the mrm_demo.exe application.
• On the MP3 Indexing tab press "Browse" and choose the files you want to index.
• Press "Start Indexing", wait until the process is finished.
• When the indexing is done you will see a prompt asking if you want to send your data to the central database. Choose "Yes" if you want to do in now (if you choose "No", you will not be able to proceed to the next step).

Important: sending indexes requires an Internet connection. No personally identifiable information will be transferred.

Test of Sloud MRM Audio Identification

The application can identify aydio records that were indexed at the same computer only. This limit not technologically-imposed but rather chosen for clarity of the test and for privacy of the testers. The step 2 above has to be completed before you can proceed with this test.

The recording volume level may happen to be too high or too low. This would cause undesirable distortions of the recorded music. In order to avoid it, the recording volume level has to be calibrated.

This requirement is imposed by the fact that we are recording audio from an analog source. If the audio is captured from a digital source, calibration is not needed. Audio Identification itself does not require calibration, only the recording does.

Recording from an audio mixer

• Start the mrm_demo.exe application. At the "Record identification" tab choose "Mixer" from the "Audio Input" list. Your actual name of the audio mixer may be different.
• Set volume of your media player to the middle position. The total volume level (lever #1 in the picture) and the level of the Wave playback (lever #2 ) in the Volume Control panel should be near maximum.
  

  

• In the media player open calibrate.wav file (in the same folder where the mrm_demo.exe is residing) and play it. In the Sloud MRM application press the "Calibrate" button.
• If the volume level happens to be non-optimal, the application will display a message "Calibration error. The playback volume is probably too low". In that case increase the volume of playback and start calibration again.
• Once the calibration is done you will to see the message: "Calibration is finished". The application is ready to identify music.

Please do not adjust playback volume after the calibration. If you do adjust it, run the calibration procedure again.

Audio Identification

• Choose any record indexed in the stage "Test of Sloud MRM Audio Fingerprinting" and start playing it back.
  IMPORTANT! The equalizer, 3D and other sound effects in the media player should be switched off.
• Open the "Record identification" tab.
• Press "Start Capture" at any time during the playback.
• Once 15 seconds or more is captured, press the "Identify" button.

The application will calculate the audioprint of the recorded sample and send it to the Sloud server for identification. The server will return the name of the previously indexed file that matches the record, as well as the contents of its tags.
