Go to function
bramslow2004_getframe
Prepares a signal for bramslow2004
Usage:
[In_Buffer, In_NoSamps, RMS_sample]=bramslow2004_getframe(y, In_FrmSize, NoFrames, Cal_RMS, UserRMS, cal_dB_SPL)
Input parameters:
| y | Input signal in the time domain. |
| In_FrmSize | Targetted frame size (in samples). |
| NoFrames | Targetted number of frames. |
| Cal_RMS | Flag. If 0, UserRMS is used for scaling. If 1, the actual RMS of the signal is used. |
| UserRMS | User RMS of input signal. |
| cal_dB_SPL | SPL of the input signal y at full scale, i.e., amplitude of \(\pm 1\), i.e., 0 dB FS. |
Output parameters:
| In_Buffer | Matrix with frames of the input signal (in Pa). Size: (In_FrmSize x NoFrames). |
| In_NoSamps | Length (in samples) of the input signal y. |
| RMS_sample | RMS of input signal y (i.e., before the scaling). |
Description:
bramslow2004_getframe(..) split input signal into a matrix of frames and scales to dB SPL as a preparation for further processing by bramslow2004.
