Response of A and C filters are fully conformant with above mentioned standards for all available frequency ranges, but in order to be have a sound level meter fully conformant with these standards a frequency range of 20 kHz or greater must be used. | Response of A and C filters are fully conformant with above mentioned standards for all available frequency ranges, but in order to be have a sound level meter fully conformant with these standards a frequency range of 20 kHz or greater must be used. | ||

The overall acoustic levels analysis requires 1 SPU per channel at 20 kHz bandwidth. The number of required SPUs is directly proportional to the analysis bandwidth (i.e. the sampling frequency divided by 2.56). | The overall acoustic levels analysis requires 1 SPU per channel at 20 kHz bandwidth.

* Source: input source to be analyzed. It may come from the Front-end input or from the Player in post-analysis mode (see the post-analysis chapter). In post-analysis mode, tracks with different signal bandwidth cannot be plugged simultaneously. | * Source: input source to be analyzed.
