The measurement type to retrieve. One of the following BassLoudness:
BASS_LOUDNESS_CURRENTLoudness in LUFS of the last 400ms or the duration (in milliseconds) specified in the HIWORD (use MakeLong(Int16, Int16)).
BASS_LOUDNESS_INTEGRATEDIntegrated loudness in LUFS. This is the average since measurement started.
BASS_LOUDNESS_RANGELoudness range in LU.
BASS_LOUDNESS_PEAKPeak level in linear scale.
BASS_LOUDNESS_TRUEPEAKTrue peak level in linear scale.

Remarks
his function is identical to BASS_Loudness_GetLevel(Int32, BassLoudness, Single) but with the ability to combine the data from multiple measurements, which can be useful for getting the overall loudness (or peak) of a group of files. Combining the measurements of multiple files is equivalent to putting those files through the same measurement one after another.

The BASS_LOUDNESS_CURRENT mode is not available when combining multiple measurements.

ERROR CODEDescription
BASS_ERROR_HANDLEhandles is not valid.
BASS_ERROR_ILLPARAMmode is not valid.
