1. 1. Audio Anomaly Detection in Cars

   University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

   Author : Asma Hussein; [2023-09-11]
   Keywords : Audio Anomaly detection; Outlier detection; Machine learning; Mel Frequency; Chroma;

   Abstract : Audio anomaly detection in the context of car driving is a crucial task for ensuring vehicle safety and identifying potential faults. This paper aims to investigate and compare different methods for unsupervised audio anomaly detection using a data set consisting of recorded audio data from fault injections and normal "no fault" driving.

3. 2. Sound Source Distance Estimation Using Sound Frequency Attenuation

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Frida Johnsson; Gillis Oldfeldt; [2023]
   Keywords : Technology and Engineering;

   Abstract : Estimating the distance between a sound source and receiver is an important problem. This thesis explores the possibility of estimating distance from a sound source using the attenuations regarding different frequencies over a distance. This method can be useful in cases where currently existing distance approxima- tion methods are not an option. READ MORE

4. 3. Estimating the risk of insurance fraud based on tonal analysis

   University essay from Lunds universitet/Matematisk statistik

5. 4. Speaker Recognition using Biology-Inspired Feature Extraction

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Edvin Andersson; [2021]
   Keywords : Artificial Intelligence; AI; Machine Learning; Speaker Recognition; Technology and Engineering;

   Abstract : Distinguishing between people's voices is something the human brain does naturally, using only frequencies picked up by the inner ear. The field of speaker recognition is concerned with making machines do the same thing using digitally sampled speech and data processing. READ MORE

6. 5. Classification of Affective Emotion in Musical Themes : How to understand the emotional content of the soundtracks of the movies?

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Paula Diaz Banet; [2021]
   Keywords : Music emotion recognition; Deep learning; Feature extraction; VGGish; Mel-frequency Cepstral Coefficients.; Music emotion recognition; Deep learning; Särdragsextraktion; VGGish; Mel-frequency Cepstral Coefficients;

   Abstract : Music is created by composers to arouse different emotions and feelings in the listener, and in the case of soundtracks, to support the storytelling of scenes. The goal of this project is to seek the best method to evaluate the emotional content of soundtracks. READ MORE
