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 widget: Widget din spectrogram na 2D yana nuna bayanan odiyo dangane da mita da lokaci, a cikin yanayin juyi-da-lokaci. Ƙirar-lokaci-lokaci na nuni yana daidaitawa ta tsawon taga na canjin Fourier (kamar mafi ƙarancin lokacin amsa widget din bakan). Hakanan an iyakance shi da ƙudurin nunin ku a cikin pixels.
- Widget din Spectrum: Widget din bakan yana nuna bayanan odiyo tare da mita. Wannan ya dace sosai don ganin halayen siginar tha: mitar asali, masu jituwa, mitocin amsawa, da sauransu. Lokacin amsawar nunin yana daidaitawa. Ana haɗa ƙaramin lokacin amsawa zuwa tsayin taga na canjin Fourier. Don FFT na maki 1024, kuma an ba da ƙimar samfurin 48000 Hz da Friture ke amfani da shi, ƙaramin lokacin amsawa shine 1024/48000 = 21.3 ms. Bugu da ƙari, widget ɗin yana zana kololuwa ga kowane ɓangaren mitar. Waɗannan kololuwa suna nuna maxima na kwanan nan na bakan, kuma suna fara raguwa jim kaɗan bayan an kai kololuwar. A ƙarshe, lakabin yana gano mitar matsakaicin matsakaicin bakan na duniya.
- Widget din Octave Spectrum: Widget din octave spectrum yana nuna bayanan odiyo tare da lokaci, kama da mai nuna dama cikin sauƙi. Ana tattara bayanan odiyo a cikin mitar kwanoni tare da faɗuwar juzu'i-na-octave. Kowanne kwandon mitar shine sakamakon juzu'i-na-octave tace.
- Widget mai iyaka: Widget ɗin iyaka yana nuna bayanan mai jiwuwa tare da lokaci. Ma'aunin lokacin yana daidaitawa. Nuni yana aiki tare tare da la'akari da babban gefen siginar da aka sanya a tsakiyar kullin lokaci, kamar yadda tsarin al'ada zai yi.
- Widget din matakin: Widget din matakin yana nuna ƙarfin kololuwa (lokacin amsawa ms 25, watau nan take) da ƙarfin RMS (lokacin amsawar ms 300) a cikin dBFS (dB Full Scale). Lokacin da yanayin tashoshi 2 ya kunna, yana nuna matakan kowane tashoshi akan sikelin daban.
