RTC Is a record time/storage size/bitrate calculator.
Uncompressed audio calculations:
Put your values time or storage size or bitrate and calculate other.
Compressed audio/video calculations:
Enter two values of bitrate/time/storage and calculate other one.
App is helpful to calculate storage volume or record time for audio and video.
Also this app can calculate bitrate/time playing/storage.
App calculates values for uncompressed audio PCM (.wav, .cda) as well as compressed audio and video (mp3, mp4, avi and e.t.c.).
Calculations are approximate for compressed audio and video.
