"What is the Web Audio API?"

"The Web Audio API is a powerful JavaScript interface for processing and synthesizing audio in web applications. It provides fine-grained control over audio playback, effects, synthesis, and analysis, enabling developers to create sophisticated audio experiences in browsers."

"How do you control audio volume with JavaScript?"

"Audio volume in JavaScript can be controlled using GainNode in the Web Audio API. Create a GainNode, connect it to your audio source and destination, then modify the gain.value property to adjust volume levels programmatically."

"What are audio oscillators in web development?"

"Audio oscillators in web development are OscillatorNode objects that generate periodic waveforms like sine, square, triangle, or sawtooth waves. They're fundamental building blocks for creating synthesized sounds and musical tones in web applications."

"How do you create audio effects with the Web Audio API?"

"Audio effects are created by chaining AudioNodes together in a processing graph. Connect oscillators, filters, delays, reverbs, and gain nodes in sequence to process audio signals and create complex sound effects and musical instruments."

"What is AudioContext and why is it important?"

"AudioContext is the main interface for Web Audio API operations. It manages audio processing, provides timing information, creates audio nodes, and handles the audio processing graph. All Web Audio operations must be performed within an AudioContext."
