Overview

Quranic Translation Audio Data is a highly curated, standardized, and streaming-optimized multilingual audio dataset containing the complete recitation of translation audios and commentaries of the Holy Quran across 51 different translation directories.

Every audio track has been meticulously converted from heavy .mp3 source files into the modern, high-fidelity Opus (.opus) format at a streaming-optimized bitrate of 32kbps. Alongside the audio, the dataset includes highly efficient Protocol Buffer (.pb) files containing word-by-word/verse-by-verse timing data for real-time syncing. This ensures crystal-clear vocal clarity while achieving maximum compression and immediate playback alignment-making it ideal for:

• —Mobile apps and offline Quranic platforms
• —Low-bandwidth/edge-computing applications
• —Multilingual Text-to-Speech (TTS) alignment and Speech Recognition (ASR) research

## Key Features

<ul> <li><b>High Vocal Fidelity</b>: Audio processed using the advanced Opus interactive audio codec, providing warm and natural voice tones despite the highly compressed size.</li> <li><b>Minimal Footprint</b>: By standardizing to 32kbps Opus, the entire dataset footprint is reduced by up to <b>65-75%</b> compared to standard MP3 formats, saving gigabytes of storage and bandwidth.</li> <li><b>Protocol Buffer Timing</b>: Binary .pb timing files are ~33% smaller than JSON and parse instantly in any language, enabling word-by-word karaoke-style highlighting.</li> <li><b>100% Complete</b>: Each language contains all 114 Surahs (chapters) from the Holy Quran, ensuring complete coverage without missing gaps.</li> <li><b>Perfect Organization</b>: Standardized 3-digit naming format (001.opus/.pb to 114.opus/.pb) mapped cleanly inside individual language folders.</li> </ul>

Dataset Structure

The dataset is organized cleanly into 51 folders, each representing a specific language translation or commentary. Inside each directory, the audio and timing files are structured as follows:
