Most of the cards that have been tested will give decent results for ordinary transfer function measurements (e.g. sound system calibration and reverberation times), except for the very high and low frequencies.
If you are going to purchase a new card we recommend that you study this document and find a suited card for your type of measurements. The Sound Blaster cards should in general work fine, note that some cards (SB Live, PCI128 and other Sound Blaster compatible cards) work best at sampling frequencies 48, 24 and 12 kHz. This is because they work internally only at 48 kHz and other sampling frequencies (except for 24 and 12 kHz) are obtained by an internal frequency conversion.
A USB device has the advantages that it can be used on a laptop, and easily be moved from one PC/laptop to another.We tested the USB device MP3+ and Creative Extigy, and were quite pleased, the price makes it a good alternative.
If you are doing high-end measurements you should read the recommendations below and also the information given below about the cards that you plan to choose.
