What could be the sample rate for 44KHz soundcard

Hey Guys,

I would like to know that what would be the amount required for RAM in order to store 4 seconds of stereo sound on a particular sound card with having 44KHz sample rate. It's having 16 bits. Can any body tell me that what would be the rate from the following list.

• 180 Kbytes
• 704 Kbytes
• 440 Kbytes
• 512 Kbytes

Does any body knows about it? Kindly suggest me your views on the above issue.

Thanks in advance

I think it would be 48kHz, because it is the part of the operating system with having standard multimedia in it.

This hardware is generally inexpensive and allows the recording of 16 bit mono/stereo signals with a sampling rate up to 44 kHz. Such high sampling rate is generally is not necessary for speech signals where most applications sampling rate 11 kHz is sufficient.

The PC is used to convert the VLF signal into an audible signal

• Soundcard runs at a sample rate of 44100 or 48000 Hz
• Frequency is converted down to an audio frequency of 650Hz (or similar)
• 650 Hz "Audio IF" is passed through a narrow-band filter (100Hz BW)
• The amplified audio is sent to the soundcard's D/A converter.
