Design of an audio signal collector based on DSP with high fidelity;

The Development of a Soft Digital Spectral Analyzer for Audio Signals;

Blind separation of mixed audio signal based on FastICA

In the emitting part of the system, the audio frequency signal is modulated through frequency modulation while the receiving part restores the primitive audio frequency signal.

Signal Analysis Based on Cantor Set and the Application of Cantor Set in Acoustic Signal of Vehicle Model Recognize;

Compared with vibration signals,acoustic signals can be collected with non-contact sensors,so as to be convenient and cheap.

On the basis of combining theory with practice, bearing fault diagnosis by acoustic signals based on Hidden Markov Model (HMM) is researched systematically in this paper.

This paper solves the problem by adaptively replacing the redundant audio signals with the chaotic synchronization signals,and presents a chaotic encryption scheme for digital audio streams.

This paper puts forward a new audio information hiding algorithm,namely partial phase division correcting method based on hearing perception experiments of wideband audio signals,which is for partial phase distortion conditions under no hearing perception difference.

This article briefly describes the characteristics of the series of chips and how it works and then puts forward by PC audio output interface and RS232 serial interface,combined with a single-chip ISD4000 series recording a voice chip bulk after all kinds of audio signals,and allows any section of the audio output.
