About the formats

Extension opus
Category Audio file formats
Developed by Xiph.Org Foundation
Mime type audio/ogg

Description

OPUS files contain audio in the lossy Opus format. It was developed for online streaming and supports variable bitrates. Similarly to MP3, which is also lossy, OPUS files do not contain an exact copy of the original audio recording. This is done to take up less space.
Extension flac
Category Audio file formats
Developed by Xiph.Org Foundation
Mime type audio/flac

Description

FLAC, or Free Lossless Audio Codec, files contain digital audio. FLAC files utilize lossless quality, meaning that there is no loss of any original sound data. When compared to MP3 (lossy audio format), FLAC files are generally larger. Nonetheless, FLAC’s lossless compression algorithm can reduce audio by up to 70%, and still be able to reproduce the original audio afterwards. The format is royalty-free.

This app is exactly what I asked for and is super easy to use. I am not a big time computer wizard so I need apps that do what they say do in a straightforward process. This app does just that! I love it and will continue to use it and will advise others or it as well. Good job to the owners/writers! And, sincere THANK YOU!

Although there are occasional errors, I was very impressed with the efforts of the developers to receive feedback from users and to improve the inconveniences quickly. I will be using it more often in the future.
