The Problem: Why It Matters

Timestamp: 1:17
Yeno shares a personal story about struggling to meet Apple’s requirements when first trying to release music.
Many artists make the mistake of submitting MP3s instead of the higher-quality WAV files, leading to poor sound quality on streaming platforms.

The lesson?
If you want your tracks to shine, start with the best possible source file.

Understanding WAV Files

Timestamp: 1:57
A WAV file is an uncompressed audio file that retains all the original data — unlike an MP3, which compresses and loses detail.

Why WAV matters:

  • No quality loss

  • Better for professional mastering

  • Required for Apple Digital Masters

If you don’t have access to a WAV file, you’ll need to go back to your original recording session or request it from your engineer.

Key highlights:

  • Setting the sample rate correctly

  • Ensuring the proper file format

  • Encoding with Apple's standards

This live walkthrough makes the process easy to follow — even if you’re new to digital mastering.

48kHz vs. 44.1kHz: Why It’s Important

Timestamp: 2:38
One major detail: Apple requires 44.1kHz sample rate for their Digital Masters — NOT 48kHz.

  • 48kHz is often used in video and film.

  • 44.1kHz is standard for high-quality music audio.

Always check your final bounce settings to make sure you're hitting 44.1kHz to avoid unnecessary rejections or quality loss.

Tools Needed for WAV File Management

Timestamp: 2:57
Yeno talks about the essential tools you need to manage and prepare WAV files, including:

  • Audio converters

  • Encoding software for AAC/M4A formatting

  • Proper mastering plugins if needed

Having the right tools makes the difference between professional-grade sound and amateur mistakes.
