Compile Quran Audio into Juz

I have the complete Quran recitation split into 114 individual Surah MP3 files. I need the collection reorganised so that it is delivered as 30 seamless Juz, still in MP3 format. No audio enhancement, noise reduction, or EQ is required—the task is strictly concatenation and accurate sequencing.

The final files should be named simply 1.mp3, 2.mp3 … 30.mp3. Each file must start exactly at the first ayah of its Juz and end at the last, with clean transitions between Surahs so playback sounds continuous.

Deliverable acceptance will be straightforward: I will spot-check several Juz to confirm correct start- and end-points, listen for gaps or overlaps, and verify the naming scheme. A shared download link for the finished 30 MP3s is fine.

Feel free to use whichever tool you prefer—ffmpeg, Audacity, Adobe Audition, or any other—as long as the final output meets the points above.
