VoIP, or Voice over Internet Protocol, is a technology that allows you to make voice calls using a broadband Internet connection instead of a traditional phone line. VoIP converts your voice into digital data packets and transmits them over the internet, providing a cost-effective and flexible alternative to conventional telephony.
We currently have a file size limit of 10 MB. Given that most voice messages are encoded with a constant bitrate and a single channel (mono, no stereo), we can calculate the maximum duration of a file using the following equation:
Applying this equation to our 10 MB limit and a bitrate of 64 kbps (commonly used by the iPhone recorder app), we arrive at a maximum duration of approximately 21 minutes and 51 seconds. To easily calculate durations for different file sizes and bitrates, you can use our audio duration calculator.
