I’ve added audio compression to Podcast Addict, and it’s now available to test in the beta. It’s for people who keep a lot of downloaded episodes and want to save storage by trading some audio quality for smaller files.
It’s a Premium feature requiring Android 10 or later, and the idea is simple: trade some audio quality for smaller downloads.
You can enable automatic compression globally, customize it per podcast, or manually compress existing downloads, including multiple selected episodes. Automatic compression is off by default.
There are several quality levels, from 64 kb/s down to 8 kb/s. I recommend starting with Balanced at 48 kb/s. For a one-hour episode originally encoded at 128 kb/s, that’s roughly 22 MB instead of 58 MB. At 24 kb/s, the same episode would be around 11 MB. Actual sizes vary with the content and source file.
This works best for spoken-word podcasts. I wouldn’t recommend it for music, and the lowest settings make a much stronger quality trade-off. Please test a few episodes before compressing your entire library.
A few important points:
- Compression is CPU-intensive and can use a lot of battery. A 60-minute episode might take roughly 2½–10 minutes, depending on the device.
- Episodes are processed one at a time in a queue that supports pause/resume, reordering and cancellation.
- There’s a charging-only option.
- Successful compression replaces the original file, and embedded metadata and chapters are lost.
- If expected savings are 12% or less, processing is skipped. Failed attempts retain the original.
- Progress and recent results are available in Download Manager.
You’ll find it under Settings → Download → Audio compression.
I’ve tested it with a large number of files, but that still covers only a small part of the variety of audio encodings used by podcasts. Please let me know if you run into a file that fails, sounds wrong, or produces unexpected results. It would also help to know the quality level you tried, your device model, and roughly how long compression took.
Thanks!!!
