    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Eriksson Janze Oscar; [2023]
    Keywords : DSP; Audio-communication; Auxiliary; AUX; phone connector; USB-audio; STM32; ADC; AD-converter; filterbank; hearing aid; signalprocessor; ljudkommunikation; ljudkabel; AUX; USB-ljud; STM32; hjälpmedel; ADC; analog-till-digital-omvandlare;

    Abstract : This thesis report is about designing a prototype and establishing audio communication between a computer and Digital Signal Processor (DSP) using two preamp circuits using both auxiliary and USB connection. The paper gives the reader an overview on how audio is transmitted from a computer, through the system and to the desired output. READ MORE

  3. 2. Microphone Array Wiener Beamformer and Speaker Localization With emphasis on WOLA Filter Bank

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Hemanth Yerramsetty; [2012]
    Keywords : RIR; Bemaforming; filterbank; srp-phat;

    Abstract : This thesis describes the design and implementation of a speech enhancement system that uses 4-channel microphone array beam forming and speech enhancement algorithms applied to a speech signal in a multiple source environment. To locate the accurate Direction of Arrival (DOA) from the source, it is necessary to design a suitable microphone array system with more efficient localization algorithm. READ MORE

  4. 3. Multichannel Wiener Filtering for Speech Enhancement in Modulation Domain

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Muhammad Awais; [2011]
    Keywords : Filterbank; Coherent Envelope Detection; Incoherent Envelope Detection; Modulation Domain; Multichannel Wiener Filtering;

    Abstract : Normally speech signals are contaminated with noise and interference that reduces the intelligibility of speech during communication. In order to make speech signals e ective and useful, they need to be enhanced from the noisy speech signal. READ MORE

  5. 4. Frekvensuppdelning med FPGA

    University essay from Institutionen för systemteknik

    Author : Pontus Ivebrink; Peter Ytterström; [2008]
    Keywords : DSP; FPGA; VHDL; FIR filter; FFT;

    Abstract : Examensarbetets syfte var att skapa ett frekvensspektrum för ljud. För att representera detta frekvensspektrum används staplar av lysdioder. Systemet implementeras på ett Altera DE2 utvecklingskort. Olika sätt för att skapa dessa frekvensuppdelningar har testats och olika metoder för att lösa dessa har också testats. READ MORE
