Audio Producer

Audio Producer Skill

I help you build audio players, process audio, and create interactive sound experiences for the web.

What I Do

Audio Playback:

• Custom audio players
• Playlist management
• Playback controls (play, pause, seek, volume)
• Waveform visualization

Audio Processing:

• Audio effects (reverb, delay, filters)
• Equalization and mixing
• Audio recording
• Real-time audio manipulation

Interactive Audio:

• Background music and sound effects
• User interaction sounds
• Spatial audio
• Audio notifications

'use client'
import { useAudioRecorder } from '@/hooks/useAudioRecorder'

export function VoiceRecorder() {
  const { recording, audioURL, startRecording, stopRecording } = useAudioRecorder()

  return (
    <div>
      <button

        className={`px-6 py-3 rounded-lg ${
          recording ? 'bg-red-600' : 'bg-blue-600'
        } text-white`}
      >
        {recording ? '⏹️ Stop Recording' : '🎤 Start Recording'}
      </button>

      {audioURL && (
        <div className="mt-4">
          <audio src={audioURL} controls />
          <a
            href={audioURL}
            download="recording.webm"
            className="mt-2 inline-block px-4 py-2 bg-green-600 text-white rounded"
          >
            Download Recording
          </a>
        </div>
      )}
    </div>
  )
}

Audio Effects

// lib/audio-effects.ts

export class AudioEffects {
  private audioContext: AudioContext
  private source: MediaElementAudioSourceNode
  private gainNode: GainNode
  private filterNode: BiquadFilterNode

  constructor(audioElement: HTMLAudioElement) {
    this.audioContext = new AudioContext()
    this.source = this.audioContext.createMediaElementSource(audioElement)
    this.gainNode = this.audioContext.createGain()
    this.filterNode = this.audioContext.createBiquadFilter()

    // Connect: source -> filter -> gain -> destination
    this.source.connect(this.filterNode)
    this.filterNode.connect(this.gainNode)
    this.gainNode.connect(this.audioContext.destination)
  }

  setVolume(value: number) {
    this.gainNode.gain.value = value
  }

  setLowPassFilter(frequency: number) {
    this.filterNode.type = 'lowpass'
    this.filterNode.frequency.value = frequency
  }

  setHighPassFilter(frequency: number) {
    this.filterNode.type = 'highpass'
    this.filterNode.frequency.value = frequency
  }

  setBandPassFilter(frequency: number) {
    this.filterNode.type = 'bandpass'
    this.filterNode.frequency.value = frequency
  }
}

Spatial Audio

// components/SpatialAudio.tsx
'use client'
import { useEffect, useRef, useState } from 'react'

export function SpatialAudio({ audioSrc }: { audioSrc: string }) {
  const audioRef = useRef<HTMLAudioElement>(null)
  const [position, setPosition] = useState({ x: 0, y: 0 })

  useEffect(() => {
    const audio = audioRef.current
    if (!audio) return

    const audioContext = new AudioContext()
    const source = audioContext.createMediaElementSource(audio)
    const panner = audioContext.createPanner()

    panner.panningModel = 'HRTF'
    panner.distanceModel = 'inverse'
    panner.refDistance = 1
    panner.maxDistance = 10000

    source.connect(panner)
    panner.connect(audioContext.destination)

    // Update panner position based on mouse/touch
    panner.setPosition(position.x, position.y, 0)
  }, [position])

  return (
    <div
      => {
        const rect = e.currentTarget.getBoundingClientRect()
        const x = ((e.clientX - rect.left) / rect.width) * 2 - 1
        const y = ((e.clientY - rect.top) / rect.height) * 2 - 1
        setPosition({ x, y })
      }}
      className="w-full h-96 bg-gray-100 rounded-lg flex items-center justify-center cursor-crosshair"
    >
      <audio ref={audioRef} src={audioSrc} controls />
      <p className="absolute text-center text-sm text-gray-600">
        Move your mouse to change sound position
      </p>
    </div>
  )
