   Author : Jacob Drotz; [2023]
   Keywords : 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;

   Abstract : 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. READ MORE

4. 8. Vocal processing of non-human characters portrayed by game masters (GMs) in tabletop role playing games (TTRPGs) : What physical attributes of a creature can be perceived in different processing?

   University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

   Author : Lina Dovner; [2023]
   Keywords : TTRPG; sound design; vocal processing; Dungeons Dragons; creature sound design; vocal modulation; orc; elf;

   Abstract : Voices reveal information about the speaker, such as their age, what they are feeling and how they look. Vocal modulation is sometimes used by role-players, mostly game masters, in a tabletop role-playing context, to portray non-playable characters. READ MORE

5. 9. Exploring State-of-the-Art Machine Learning Methods for Quantifying Exercise-induced Muscle Fatigue

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Abboud Afram; Danial Sarab Fard Sabet; [2023]
   Keywords : EMG; SEMG; STFT; CWT; SVM; CNN; GAN; DCGAN; BCE; SGD; deep learning; machine learning; muscle fatigue; DCGAN; spectrogram; CNN models; transfers learning; data augmentation; feature extraction;

   Abstract : Muscle fatigue is a severe problem for elite athletes, and this is due to the long resting times, which can vary. Various mechanisms can cause muscle fatigue which signifies that the specific muscle has reached its maximum force and cannot continue the task. READ MORE

6. 10. Real-time Autofocus Algorithm in Laser Speckle Contrast Imaging

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Giovanni Russo; [2023]
