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.
- Ngwa Spectrum: Ngwa dị iche iche na-egosiputa data ọdịyo yana ugboro ole. Nke a dabara nke ọma iji anya nke uche hụ njirimara nke mgbama tha: isi ugboro, ihe nkwekọ, nzaghachi nzaghachi, wdg. Oge nzaghachi nke ngosi bụ nhazi. Ejikọtara oge nzaghachi kacha nta na ogologo windo nke mgbanwe Fourier. Maka FFT nke isi 1024, ma nye ọnụego nlele nke 48000 Hz nke Friture na-eji, oge nzaghachi kacha nta bụ 1024/48000 = 21.3 ms. Na mgbakwunye, wijetị na-adọta ọnụ ọgụgụ kacha elu maka akụrụngwa ugboro ole ọ bụla. Ọnụọgụ ndị a na-aka akara kachasị nke ụdịdị dị iche iche na nso nso a, ma na-amalite ibelata obere oge ka emechara elu ahụ. N'ikpeazụ, akara na-achọpụta ugboro nke kacha nke ụdịdị dị iche iche zuru ụwa ọnụ.
- 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.
