Šio darbo tikslas suprojektuoti ir sukurti nesudėtingą garsinio signalo apdorojimo realiu laiku įtaisą, populiaraus „Arduino“ mikrovaldiklio pagrindu, kuriuo būtų lengva naudotis ir būtų galimybė pagrindines funkcijas valdyti naudojantis TC/IP protokolu. „Arduino“ mikrovaldiklis pasirinktas dėl jo populiarumo, prieinamos kainos ir dėl gausios informacijos, apie jo panaudojimo galimybes. Be abejo yra daug ir kitų platformų skirtų įvairių prietaisų kūrimui su pakankamai išsamia informacija, bet „Arduino“ platformai yra sukurta nemokama atviro kodo programinė įranga, „Arduino“ kontrolerio programavimui tiesiogiai iš personalinio kompiuterio, nenaudojant papildomų priemonių, dirbanti su Windows ir Unix operacinėmis sistemomis. / Most modern desktop computers are equipped with audio hardware. This hardware allows audio to be recorded as digital information for storage and later playback. This digital information can be manipulated to change how the audio sounds when played back. But if we don’t have a computer, or just need to get some sound effects quickly without recording audio? Maybe You are a student who are learning sound processing hardware and need some examples of audio synthesis? Do you like an “Arduino” and want to see what it can? This device is for You! This small device based on “Arduino” controller makes audio processing in real time, producing some audio effects and also it can play some synthetic sound. In this device is integrated LCD screen, where you can see some information about what the device is doing, when you have pressed one of some buttons on it. Also it is possible to manage the device over the internet. You need just plug in an Ethernet cable, open an internet browser on the computer in local network and add an IP address of this device. You will get small web page where you will found few buttons. By clicking with mouse on these buttons you can listen to a synthetic sound, which system can produce. In this work You will be introduced to the sound signal processing. You will also find graphs and flowchart detailing the sequence of event between the user and system, the exchange of data inside and the static structure of the system in the architectural specification.
