Alternative styles of graph are provided, lines or filled.
There are two movable target lines for reference levels.
Full scale may be set as required, for instance, as an SPL meter using a microphone you may want full scale to read 90dB, while for audio levels on a line input you may want 0dB as shown above.
Note: The response is essentially flat up to 20kHz. ‘A’ and ‘C’ weighting is not included at present.
The role of dBview is to measure the volume of sound, essentially a replacement for a traditional Sound Pressure Level meter. Note however it needs to be calibrated using a real SPL meter for accurate results. Originally desgined for use in speech therapy using a microphone it can have other applications including audio level from a line input.
Features
- Shows level on a graph which displays approximately 12 seconds back in time.
- Graph can show an average or transient peaks and troughs, or both.
- Lines show the volume of a target zone to try and keep within
- Numeric display reads levels averaged over a short period and also an average for the duration of the entire test.
- Starting and stopping each test can be done with a tap of the space-
bar or using sound level activation. - Up to 2 minutes from the start of a test is recorded and can be replayed instantly
