  1. 1. Approach for frequency response-calibration for microphone arrays

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Jacob Drotz; [2023]
    Nyckelord :microphone array; frequency response; calibration; sine sweep; inverse filter; digital signal processing DSP ; convolution; Fast Fourier Transform FFT ; Discrete Fourier Transform DFT ; acoustic measurements; audio engineering; mikrofonarray; frekvenssvar; kalibrering; sinussvep; inverterat filter; digital signalbehandling; faltning; Fast Fourier Transform FFT ; Discrete Fourier Transform DFT ; akustiska mätningar; ljudteknik;

    Sammanfattning : Matched frequency responses are a fundamental starting point for a variety ofimplementations for microphone arrays. In this report, two methods for frequencyresponse-calibration of a pre-assembled microphone array are presented andevaluated. LÄS MER

  3. 2. Implementation and Comparative Analysis of Head-Related and Binaural Room Impulse Response in a Mid-Side Decomposition

    Master-uppsats, KTH/Teknisk akustik

    Författare :Jonathan Ling; [2023]
    Nyckelord :Master’s Thesis; Spatial audio; Sound Externalisation; Binaural recording; Headphones; Mid-Side Processing; Masteruppsats; Rumsligt Ljud; Ljud-externalisation; Binaural Inspelning; Hörlurar; Mid-Sid processering;

    Sammanfattning : This thesis aimed to clarify the essential factors involved in externalising audio over headphones. Extensive research was conducted, examining binaural cues and the latest advancements in the field. A novel approach was proposed, which applied HRIRs and BRIRs on a Mid-Side decomposition. LÄS MER

  4. 3. Analysis of speaking time and content of the various debates of the presidential campaign : Automated AI analysis of speech time and content of presidential debates based on the audio using speaker detection and topic detection

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Axel Valentin Maza; [2023]
    Nyckelord :Artificial Intelligence; Speaker detection; Speaker recognition; Speaker diarization; Speaker identification; Debate; Politics; Deep Learning; Artificiell intelligens; talardetektion; talarigenkänning; talardiarisering; talaridentifiering; debatt; politik; djupinlärning;

    Sammanfattning : The field of artificial intelligence (AI) has grown rapidly in recent years and its applications are becoming more widespread in various fields, including politics. In particular, presidential debates have become a crucial aspect of election campaigns and it is important to analyze the information exchanged in these debates in an objective way to let voters choose without being influenced by biased data.

  5. 4. Room Impulse Response Interpolation

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Daníel Thor Wilcox; [2023]
    Nyckelord :Virtual Acoustics; Machine Learning; Signal Processing; Room Impulse Response; Virtuell Akustik; Maskininlärning; Signalbehandling; rumsimpulssvar;

    Sammanfattning : In Virtual Reality (VR) systems, the incorporation of acoustics allows for the generation of audio-visual stimuli, facilitating applications in engineering, architecture, and design. The goal of virtual acoustics is to create a realistic sound field in continuous space. LÄS MER

  7. 5. Understanding the differences between reverberation and delay on vocals in live music scenarios : A study on the perceptions and preferences of the live concert audience

    Kandidat-uppsats, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Tom Kristoffersson; [2023]
    Nyckelord :Live music; sound engineering; audio; vocal processing;

    Sammanfattning : Two common vocal processing techniques in pop- and rock music are the use of artificial reverberation or delay. The differences between these effects have been thoroughly studied in the studio environment (Case, 2007; Henriques & Rietveld, 2018; Ronen, 2015), but research is lacking in the live realm. LÄS MER
