Using Pulse-Width Modulation and Audio Sampling Techniques to Construct an Audio Player with a Field-Programmable Gate Array John C. Greavu III University of Minnesota‚ School of Physics and Astronomy I. INTRODUCTION 8-bit and 16-bit audio players were built by employing pulse-width modulation (PWM) techniques with a field-programmable gate array (FPGA). Basic PWM and audio playing methods are explained in detail. A sigma-delta modulation module‚ specifically‚ was programmed into a Basys

Audio Equalizer Research Audio Equalization Equalization‚ or EQ for short‚ means boosting or reducing (attenuating) the levels of different frequencies in a signal. The most basic type of equalization familiar to most people is the treble/bass control on home audio equipment. The treble control adjusts high frequencies‚ the bass control adjusts low frequencies. This is adequate for very rudimentary adjustments — it only provides two controls for the entire frequency spectrum‚ so each control

4 The Audio-Lingual Method (Pages 35-51) 1- Compare and contrast the Direct Method and the Audio-Lingual Method. (1) Both are oral-based approaches. (2) The Direct Method emphasizes vocabulary acquisition through exposure to its use in situations; the Audio-Lingual Method drills students in the use of grammatical sentence patterns. (3) Unlike the Direct Method‚ the Audio-Lingual Method has a strong theoretical base in linguistics and psychology. 2- How has the behavioral psychology influenced

How quickly the microphone reacts to a sound wave and specifically to those transients just described. This differentiates one mic sound from another. Condenser mics typically have the best transient response. Preamp- A control used to boost an audio Signal’s level. Microphones are plugged into preamps. The preamp knob is turned up to a useable and desired signal level. This level is generally sent to a recorder or a set of speakers. Bleed- The amount of sound that bleeds into the source

THE AUDIO - LINGUAL METHOD 1. INTRODUCTION Basically‚ The Audio-Lingual Method is like The Direct Method; however‚ it is very different in that rather than emphasizing vocabulary acquisition through the situation. The Audio-Lingual Method more emphasizing to drill students in the use of grammatical pattern; therefore‚ it is also not same like The Direct Method which has a strong theoretical base in linguistic and psychology. When the teacher teaches students they have to know that the way to

Garrison Katz The Concepts of Audio‚ Engineering “The most important thing about audio engineering is to understand the concepts of mixing. Since there are so many concepts finding the best one in general will be hard‚ I myself don’t think it exists yet”(May). From the dawn of time mankind has had music and every song since the first one is known as the infinity remix.
