Did you know that when you exchange files via LINE for music production, sending a music file directly in the message field compresses it automatically and degrades the sound? Even high-quality audio files such as WAV lose quality through this compression, and in some cases can no longer be loaded into a DAW. The solution is simple: compress the file into a format such as Zip before sending it via LINE, and it will reach the other person with its quality intact.
Does the Sound Degrade When You Exchange Files via LINE?

These days it is harder to find someone who does not use the messaging app "LINE."
Many of you probably use LINE to communicate about music production as well.
It is very convenient and I use it often too, but there is something to watch out for when exchanging music files.
LINE can send not only messages but also files of up to 1 GB. However, if you send music files, including WAV, directly in the message field, the files are automatically compressed and the sound degrades.

As you can see, the file size is drastically reduced, and of course the sound degrades too.

In some cases, the file cannot be loaded into a DAW at all.
The solution is simple.

When sending music files via LINE, always compress them into a format such as "Zip" first.
This lets you deliver the files to the other person exactly as they are.
Frequently Asked Questions
Q1. Why do WAV files degrade when sent via LINE?
LINE's message feature automatically compresses files when they are sent, lowering the original file quality. It is not suited to high-quality audio production.
Q2. Does simply compressing into Zip prevent the quality loss?
Yes. Compressing into Zip format before sending via LINE prevents the file from being recompressed, so the original quality is preserved.
Q3. Is it fine if I use LINE's 1 GB file sending feature?
It gets around the size limit, but files sent in the message field are still compressed automatically, so the sound degrades. Always compress into Zip.
Q4. Are there other safe ways to share files?
Cloud storage such as Google Drive or Dropbox lets you share high-quality files without compression. They are recommended for music production.
