幾つかの音声ファイルの音質が不明瞭なのですが・・・

When downloading audio from LingQ, I feel that it is more irritating than the sound downloaded from TheLinguist.

Actually, when uploading an audio file, it seems that some uploaded at the wrong bit rate were mixed. Currently checking the audio files in the store, correcting the bit rate and re-uploading it. If you have contents saying “This sound file is also bad sound quality!”, Would you please contact customer service by all means?
