60db

Official 60db SDK for JavaScript/TypeScript

Installation

npm install 60db

Quick Start

import { SixtyDBClient } from '60db';

const client = new SixtyDBClient('your-api-key');

Features

🎤 Text-to-Speech

Basic TTS (returns ArrayBuffer):

const audio = await client.textToSpeech({
  text: 'Hello, world!',
  voice_id: 'your-voice-id',
  speed: 1.0,        // 0.5 to 2.0 (default 1.0)
  pitch: 0,          // -10 to 10 (default 0)
  stability: 1,      // 0 to 1 (default 1)
  boost_volume: false,
  sample_rate: 24000
});

Streaming TTS (real-time chunks):

await client.textToSpeechStream(
  {
    text: 'This is a streaming example.',
    voice_id: 'your-voice-id',
    sample_rate: 24000
  },
  {
    onChunk: (chunkIndex, totalBytes) => {
      console.log(`Progress: ${chunkIndex} chunks, ${totalBytes} bytes`);
    },
    onRawChunk: (pcmBytes, sampleRate) => {
      console.log(`Received: ${pcmBytes.length} bytes at ${sampleRate}Hz`);
    },
    onComplete: (wavUrl, sampleRate, totalPcmBytes) => {
      console.log(`Complete! WAV: ${wavUrl}`);
      console.log(`Duration: ${totalPcmBytes / (sampleRate * 2)} seconds`);
    },
    onError: (error) => {
      console.error('Error:', error);
    }
  }
);

🤖 Chat Completions (LLM)

Non-streaming (simple):

const response = await client.chat.completions.create({
  model: 'qcall/slm-3b-int4',
  messages: [
    { role: 'system', content: 'You are a helpful assistant.' },
    { role: 'user', content: 'What is 60db?' }
  ],
  stream: false
});

console.log(response.choices[0].message.content);

Streaming (real-time):

const stream = await client.chat.completions.create({
  model: 'qcall/slm-3b-int4',
  messages: [
    { role: 'system', content: 'You are a helpful assistant.' },
    { role: 'user', content: 'Tell me a joke' }
  ],
  stream: true
});

for await (const chunk of stream) {
  if (chunk.choices?.[0]?.delta?.content) {
    process.stdout.write(chunk.choices[0].delta.content);
  }
}

Custom parameters:

const response = await client.chat.completions.create({
  model: 'qcall/slm-3b-int4',
  messages: [
    { role: 'user', content: 'Explain AI briefly' }
  ],
  top_k: 50,                           // Default: 100
  chat_template_kwargs: {
    enable_thinking: true              // Enable thinking mode
  },
  stream: false
});

🎧 Voices

// List all voices
const voices = await client.getVoices();
console.log('Total voices:', voices.data.cloned_voices.length);

// Get specific voice
const voice = await client.getVoice(voiceId);

🌍 Languages

const languages = await client.getLanguages();
// Returns: [{ language_id: 'en', name: 'English' }, ...]

🎤 Speech-to-Text

const result = await client.speechToText(audioFile, {
  language: 'en'
});

Configuration

const client = new SixtyDBClient({
  apiKey: 'your-api-key',
  baseUrl: 'https://api.60db.ai'  // Optional, default shown
});
