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: 2D SpecternSpe tawm cov ntaub ntawv tawm suab thiab lub sijhawm, hauv lub sijhawm yob-tawm tsam. Lub sijhawm-zaus daws teeb meem ntawm cov zaub yog tsau los ntawm lub qhov rai ntev ntawm cov neeg hloov chaw ntawm lub sijhawm hloov chaw ntawm Spectrum widget). Nws tseem raug txwv los ntawm kev daws teeb meem ntawm koj cov zaub hauv pixels.
- Spectrum widget: lub spectrum widget qhia cov ntaub ntawv audio tiv me ntsis. Qhov no yog qhov tsim nyog heev kom pom cov yam ntxwv ntawm thacital: kev ua haujlwm ntau zaus, kev sib haum xeeb, thiab lwm yam. Lub sijhawm teb ntawm cov zaub yog teeb tsa. Lub sijhawm tsawg kawg nkaus yog txuas rau lub qhov rai ntev ntawm cov neeg hloov pauv Fourier. Rau fFT ntawm 1024 cov ntsiab lus, thiab muab cov qauv ntsuas ntawm 48000 hz siv los ntawm qhov tsawg kawg nkaus lub sij hawm yog 1024/48000 = 21.3 ms. Ib qho ntxiv, tus widget kos peaks rau txhua zaus. Cov ntsiab lus no tau cim tsis ntev los no Maxima ntawm lub spectrum, thiab pib txo qis dua tom qab lub ncov tau mus txog. Thaum kawg, daim ntawv lo qhia tias muaj ntau zaus ntawm lub ntiaj teb siab tshaj plaws ntawm lub spectrum.
- Octave spectrum widget: lub octave spectrum widgays cov ntaub ntawv audio tiv lub sijhawm, zoo sib xws rau cov spectrum widget. Cov ntaub ntawv Audio tau ua pawg nyob rau hauv zaus hauv cov pob muaj nrog feem-Octave dav. Txhua zaus dhau los yog qhov tshwm sim ntawm feem-ntawm-octave lim.
- Cov Qauv Dav Dav: Cov Scope widgplays cov ntaub ntawv tawm suab tiv lub sijhawm. Lub sijhawm ntsuas yog kev teeb tsa. Cov zaub yog synchronized nrog rau kev coj ua-ntug ntawm daim paib muaj npe nyob rau hauv lub chaw ntawm lub sijhawm Axis, raws li ib txwm muaj kev yuav ua.
- Qib Widget: Qib Widget qhia txog lub zog siab (25 ms teb lub sijhawm, i. Instantaneous lub sijhawm (300 ms lub sijhawm teb (DB tag nrho teev). Thaum hom 2-channel yog qhib, nws qhia cov qib ntawm txhua channel ntawm ib qho kev sib cais.
