What is a "Voice Recorder Sd Card"? The Most Authoritative Explanation.
How do I choose the best microSD card for audio voice recorders?
The most important consideration when looking for a microSD card for your audio voice recorder is file system compatibility. And the SD standard does a very poor job of informing consumers which system file formats supported by each SD standard.
What is the highest bitrate an SD card can record audio at?
The highest bitrate audio it can record is 96kHz/24bit stereo WAV recording. That equates to 96,000 Hz X 24 bit X 2 channels = 4,608,000 bps, which is equivalent to 0.576MB/s (that’s MegaBytes per second!). Now, the default/lowest SD bus speed was defined by the SD1.0 specification as 12.5MB/s.
How many hours of audio can a 32GB SD card record?
With the 32GB Ultra, you’ll be able to record about 48 hours of 44.1kHz/16 bit Wav audio and 350 hours of 192kbps mp3 audio. Buy the 32GB SanDisk Ultra now from Amazon.
