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:
- Widget ya 2D Spectrogram: Widget ya 2D spectrogram imawonetsa ma audio motsutsana ndi ma frequency ndi nthawi, m'njira yopitilira nthawi. Kusintha kwanthawi pafupipafupi kwa chiwonetserochi kumakhazikitsidwa ndi kutalika kwazenera kwa kusintha kwa Fourier (monga nthawi yocheperako kuyankha kwa widget ya sipekitiramu). Zimachepetsedwanso ndi mawonekedwe a chiwonetsero chanu mu ma pixel.
- Widget ya Spectrum: Widget yowoneka bwino imawonetsa ma audio motsutsana ndi ma frequency. Izi ndizoyenera kwambiri kuti muwone mawonekedwe a chizindikiro cha tha: pafupipafupi, ma harmonics, maulendo obwereza, ndi zina zotero. Nthawi yoyankhidwa yawonetsero ndi yosinthika. Nthawi yochepa yoyankha imalumikizidwa ndi kutalika kwazenera kwa kusintha kwa Fourier. Pa FFT ya mfundo za 1024, ndikupatsidwa zitsanzo za 48000 Hz zogwiritsidwa ntchito ndi Friture, nthawi yochepa yoyankha ndi 1024/48000 = 21.3 ms. Kuphatikiza apo, widget imakoka nsonga za gawo lililonse la ma frequency. Zinsombazi zimawonetsa kukula kwaposachedwa kwa sipekitiramu, ndipo zimayamba kuchepa patangopita nthawi yayitali. Pomaliza, chizindikiro chimazindikiritsa kuchuluka kwa sipekitiramu yapadziko lonse lapansi.
- Widget ya Octave Spectrum: Widget ya octave spectrum imawonetsa zomvera ndi nthawi, mofanana ndi widget ya Spectrum. Zambiri zamawu zimayikidwa m'mabini afupipafupi okhala ndi magawo ang'onoang'ono a octave wide. Bini iliyonse yama frequency ndi zotsatira za fyuluta ya octave.
- Widget ya Scope: Widget yayikulu imawonetsa zomvera ndi nthawi. Nthawi sikelo ndi configurable. Chiwonetserochi chimagwirizanitsidwa ndi kutsogolo kwa chizindikiro chomwe chili pakati pa nthawi, monga momwe chikhalidwe chimachitira.
- Widget ya mulingo: Widget ya mulingo imawonetsa mphamvu zapamwamba (nthawi yoyankha 25 ms, mwachitsanzo, nthawi yomweyo) ndi mphamvu ya RMS (nthawi yoyankha 300 ms) mu dBFS (dB Full Scale). Njira ya 2-channel ikayatsidwa, imawonetsa milingo ya tchanelo chilichonse pamlingo wosiyana.
