<strong>XL2</strong> <strong>Analyzer</strong> <strong>records</strong> <strong>high</strong>-<strong>resolution</strong> <strong>Wav</strong>-<strong>files</strong> <strong>with</strong> EAP-<strong>Option</strong><br />
The <strong>XL2</strong> Audio and Acoustic <strong>Analyzer</strong> now <strong>records</strong> linear, <strong>high</strong>-<strong>resolution</strong> wav<strong>files</strong><br />
in 24 Bit / 48 kHz <strong>resolution</strong> <strong>with</strong> the optional Extended Acoustic Pack<br />
(EAP). At the same time the <strong>XL2</strong> measures the sound levels of the monitored<br />
live sound or environmental noise, thus audio and level data are stored<br />
simultaneously on the Mini-SD-Card. This ideally suits acousticians for further<br />
post processing or detailed analysis on the computer.<br />
The <strong>high</strong>-<strong>resolution</strong> wav-file recording of the <strong>XL2</strong> <strong>Analyzer</strong> is especially an advantage<br />
for environmental noise monitoring. The <strong>XL2</strong> logs the actual sound levels and also<br />
<strong>records</strong> the wav-file together on the Mini-SD-Card. All data may be quickly<br />
transferred to a third party wav-file editor or post processing software via the USB<br />
interface or directly from a card reader. The wav-file format is mono, 24 Bit <strong>resolution</strong><br />
<strong>with</strong> 48 kHz sampling rate. The post processing <strong>with</strong> third party editing software on<br />
the computer allows removing segments of unwanted sound sources from the logged<br />
audio data and calculates the required sound level results. These post-processed<br />
results may be compared <strong>with</strong> the various simultaneously stored measurement<br />
results of the <strong>XL2</strong> <strong>Analyzer</strong>. The <strong>XL2</strong> logs all sound levels in A, C, Z weighting at<br />
once. Together <strong>with</strong> the optional Extended Acoustic Pack also the percentile statistics<br />
are available.<br />
Live Sound monitoring <strong>with</strong> ADPCM <strong>Wav</strong>-<strong>files</strong><br />
For applications not requiring the linearity of 24 Bit / 48 kHz <strong>resolution</strong>, or where it is<br />
desirable to minimize file size, the basic <strong>XL2</strong> <strong>Analyzer</strong> already generates ADPCM<br />
compressed wav-<strong>files</strong>. These are typically used for monitoring of live sound events or<br />
for violation logging in community sound measurements. For example suppose that<br />
an excessive sound level of 115 dBA has been measured at a live event, but perhaps<br />
this sound level has actually been caused by people shouting close to the<br />
measurement microphone: Examination of the recorded wav-file and logged test<br />
results from the <strong>XL2</strong> Audio and Acoustic <strong>Analyzer</strong> will show that the actual normal<br />
sound level was below the maximum permitted sound level of e.g. 99 dBA throughout<br />
the event. The <strong>XL2</strong> <strong>Analyzer</strong> generates all data for later verifications, thus simplifying<br />
monitoring of live sound events.<br />
