NKỌWA:
Friture is a real-time audio analyzer. The purpose of Friture is to help analyze an audio signal to understand the characteristics of this signal (fundamental, harmonics, feedback, etc.), to describe the source/room/receiver behaviour (reverberation, gain peaks, etc.), or to make adjustments in the preprocessing (room equalization). This is achieved by providing a set of widgets to visualize audio data:
- 2D Spectrogram wijetị: wijetị spectrogram 2D na-egosiputa data ọdịyo ma ugboro na oge, n'ụdị ntụgharị-emegide oge. A na-edozi mkpebi ugboro ugboro nke ihe ngosi site na ogologo windo nke mgbanwe Fourier (dịka maka oge nzaghachi kacha nta nke wijetị dị iche iche). A na-amachikwa ya site na mkpebi ngosipụta gị na pikselụ.
- Spectrum widget: The spectrum widget displays audio data versus frequency. This is very appropriate to visualize the characteristics of tha signal: fundamental frequency, harmonics, feedback frequencies, etc. The response time of the display is configurable. The minimum response time is linked to the window length of the Fourier transform. For a FFT of 1024 points, and given the sampling rate of 48000 Hz used by Friture, the minimum response time is 1024/48000 = 21.3 ms. Additionally, the widget draws peaks for each frequency component. These peaks mark the recent maxima of the spectrum, and start to decrease shortly after the peak was reached. Finally, a label identifies the frequency of the global maximum of the spectrum.
- Ngwa wijetị Octave Spectrum: wijetị octave spectrum na-egosiputa data ọdịyo na oge, n'otu aka ahụ na wijetị Spectrum. A na-achịkọta data ọnụnụ n'ime ntụtụ ugboro nwere obosara-nke-octave. Ihe nzacha ugboro ọ bụla bụ nsonaazụ nke nzacha-nke-octave.
- Ngwa wijetị oke: obosara wijetị na-egosiputa data ọdịyo na oge. Enwere ike ịhazi ọnụ ọgụgụ oge. A na-emekọrịta ihe ngosi n'akụkụ akụkụ mgbama nke edobere n'etiti etiti oge, dịka mpaghara ọdịnala ga-eme.
- Ngwa wijetị ọkwa: Wijetị ọkwa ọkwa na-egosiputa ike kacha elu (oge nzaghachi ms 25, ya bụ ozugbo) yana ike RMS (oge nzaghachi ms 300) na dBFS (dB Full Scale). Mgbe agbanyere ụdị ọwa 2, ọ na-egosiputa ọkwa nke ọwa ọ bụla na ọkwa dị iche.
