An audio signal is a signal that contains information in the audible frequency range. Audio representation refers to the extraction of audio signal properties, or features, that are representative of the audio signal composition (both in temporal and spectral domain) and audio signal behavior over time. Feature extraction is typically combined with feature selection, …

• CD audio usually uses – 44,100 samples / second – accuracy of 1 in 65,536 (= 2^16) distinct levels – two samples at each time for stereo – data rate is 44,100 x 2 x 16 bits/sample = 1,411,200 bits/sec = 176,400 bytes/sec ~ 10.6 MB/minute • MP3 audio compresses by clever encoding and removal of sounds that won't really be heard – data rate is ~ 1 MB/minute

Audio Representation The Wolfram Language provides fully integrated audio support, including fast and efficient in-memory data, as well as large out-of-core local and remote files. The built-in audio enables a range of uses, from immediate playing and scrubbing to advanced programmatic processing and analysis.

Auditory Stream refers to a perceptual unit associated with a single happening (A.S. Bregman, 1990) . Acoustic to Neural Conversion Organize into Auditory Streams Representation of Reality Computer Interpretation In order for a computer algorithm to interpret a scene Acoustic signals must be converted to numbers using meaningful models.

https://arxiv.org/abs/2202.03587
17 hours ago · Deriving multimodal representations of audio and lexical inputs is a central problem in Natural Language Understanding (NLU). In this paper, we present Contrastive Aligned Audio-Language Multirate and Multimodal Representations (CALM), an approach for learning multimodal representations using contrastive and multirate information inherent in audio and …
