@saraudio/vue

Vue 3 Composition API bindings for SARAUDIO audio pipeline.

Installation

pnpm add @saraudio/vue @saraudio/runtime-browser

Usage

<script setup lang="ts">
import { useRecorder, useMeter } from '@saraudio/vue';
import { vadEnergy } from '@saraudio/vad-energy';
import { meter } from '@saraudio/meter';

const rec = useRecorder({
  stages: [vadEnergy({ thresholdDb: -50 }), meter()],
  segmenter: { preRollMs: 300, hangoverMs: 500 },
});

const meterLevels = useMeter({ pipeline: rec.pipeline });
</script>

<template>
  <button @click="rec.start()">Start</button>
  <button @click="rec.stop()">Stop</button>

  <p>Status: {{ rec.status }}</p>
  <p>Segments: {{ rec.segments.length }}</p>

  <div v-if="rec.vad">
    <p>Speech: {{ rec.vad.speech ? 'Yes' : 'No' }}</p>
  </div>

  <div v-for="segment in rec.segments" :key="segment.id">
    {{ segment.id }}
  </div>
</template>

Note: Runtime is created automatically. You can optionally pass your own:

<script setup lang="ts">
import { useRecorder } from '@saraudio/vue';
import { createBrowserRuntime } from '@saraudio/runtime-browser';

const runtime = createBrowserRuntime();
const rec = useRecorder({ runtime, stages: [...] });
</script>
