Detailed Description

Level measurement information.

Description:

Structure used for acquiring the bus level measurement information.
This is used in the criAtomExAsr_GetBusAnalyzerInfo function.

Remarks:

Each level value is the scaling factor for the amplitude of the sound data (unit is not decibel).
The value can be converted into a decibel notation by using the following code.
dB = 10.0f * log10f(level);

Field Documentation

num_channels

CriSint32 num_channels

Number of valid channels.

Description:

Specifies the number of channels with valid measurement results.

rms_levels

CriFloat32 rms_levels[CRIATOMEXASR_MAX_CHANNELS]

RMS level.

Description:

Calculated RMS (root mean square) of the sound amplitude within a measurement interval.
This is handled as the sound pressure level.

peak_levels

CriFloat32 peak_levels[CRIATOMEXASR_MAX_CHANNELS]

Peak level.

Description:

Maximum value of the sound amplitude within a measurement interval.

peak_hold_levels

CriFloat32 peak_hold_levels[CRIATOMEXASR_MAX_CHANNELS]

Peak hold level.

Description:

Peak level value being held.
