About EAC3 files
E-AC3 (Enhanced AC-3) is an advanced audio codec developed by Dolby, extending the capabilities of standard AC3. It supports higher bitrates, more audio channels (up to 7.1), and improved compression efficiency while maintaining backward compatibility. E-AC3 is commonly used in Blu-rays, streaming services, and digital broadcasts for immersive surround sound. Though still a lossy format, it offers better audio quality than AC3, particularly for complex soundscapes, making it a preferred choice for high-fidelity home theater systems.
About PCM files
PCM (Pulse Code Modulation) is the standard digital audio format that represents sound waves as numerical values. It's uncompressed, maintaining perfect audio quality but creating large file sizes. PCM serves as the basis for formats like WAV and CD audio, widely used in professional recording and broadcasting. Though not space-efficient, its lossless nature makes it ideal for high-fidelity audio applications where quality preservation is crucial.

To correctly play the PCM file you converted, set the playback parameters as:

  1. Format: s16le (signed 16-bit little-endian),
  2. Sample rate: 44100 Hz,
  3. Channels: 2 (stereo)

Since it's raw PCM with no headers, players like ffplay must be run with: ffplay -f s16le -ar 44100 -ac 2 out.pcm. In Audacity, import as raw and select the same settings.

Batch Convert EAC3 to PCM Online

With this SoConvert tool, you can convert multiple EAC3 files to PCM directly in your browser for free. You can also adjust the audio Bitrate during conversion.

Click the Options button in the top-right corner to open the settings panel, where you can customize the output PCM audio Bitrate.

Other Settings Explained:

  • Encoding Speed: Choose the encoding speed. Faster speeds result in larger file sizes.
  • Audio Bitrate: Recommended range is 8 – 320 Kbps.
  • Cut Audio: Trim the audio using a start and end time in HH:MM:SS format. For example, setting 00:00:05 to 00:00:08 will cut a 3-second clip from the audio.

    • Before converting, you can choose a local folder to save the converted PCM files. Once an EAC3 file is successfully converted, it will be automatically saved to your selected directory—no manual download required.

    Save All: After all EAC3 files are converted, click “Save All” to export every PCM file to your chosen folder in one go.
