Data Types

FIR

For storing impulse responses.

Note: Delay is mandatory (set to 0 if not used).

Name Default Flags Dimensions Type Comment
GLOBAL:DataType FIR rm attribute
Data.IR 0 m mRn double Impulse responses
Data.SamplingRate 48000 m I double Sampling rate of the samples in Data.IR
Data.SamplingRate:Units hertz m attribute Unit of the sampling rate
Data.Delay 0 m IR, MR double Additional delay of each IR in samples

TF

Useful to describe a transfer function by a sparse number of frequencies. The guys from BEM simulations like it.

Note: the dimensional variable N is mandatory, it must be of dimension N, and must provide the frequency values.

Name Default Flags Dimensions Type Comment
GLOBAL:DataType TF rm attribute
Data.Real 0 m mRn double The real part of the complex spectrum
Data.Imag 0 m MRN double The imaginary part of the complex spectrum
N 0 m N double Frequency values
N_LongName frequency attribute
N_Units hertz m attribute Unit of the values given in N


FIRE

FIRE is based on FIR and is intended for storing impulse responses which depend on the emitter (E).

Note: Delay is mandatory (set to 0 if not used).

Name Default Flags Dimensions Type Comment
GLOBAL:DataType FIRE rm attribute
Data.IR 0 m mREn double Impulse responses
Data.SamplingRate 48000 m I double Sampling rate of the samples in Data.IR
Data.SamplingRate:Units hertz m attribute Unit of the sampling rate
Data.Delay 0 m IR, MR double Additional delay of each IR in samples
