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.
