With 96khz the human ear is hardly able to differentiate that extra quality of sound so with 44 khz I suppose they are enough for sound quality, right? or am I wrong?
Hi Luis,
the highest audio frequency that can be processed is around
half the sampling frequency. At 44.1 and 48 kHz these are about 22 and 24 kHz. This is ready above the human hearing range. In principle 44.1 or 48 kHz are sufficient. But in the (semi-) professional area, 96 kHz is often used. Normally, it's not just about simple recording and playback, but the digital audio data should also be processed and mixed.
However, I consider the recording resolution to be much more important than the sampling frequency, i.e. the maximum number of "steps" that a digital value can assume during recording. A 24-bit recording is clearly superior to a 16-bit recording (of course also at 44.1 kHz sampling frequency).
A "USB audio cable" (2 * 6.3 mm mono jack plugs to USB type A plug) is also an external audio interface (only that the A/D converter electronics are built into the USB connector). These simple "audio interface cables" mostly work with 44.1 kHz / 16-bit. However, it is not only a matter of these technical values, but above all of the quality of the A/D converter. This is decisive as to how the signal converted from analog to digital "sounds" later.
Such an "audio interface cable" can be sufficient for simple applications, but I still recommend a "real" audio interface, which is now available in good quality and very inexpensive (around 50 and 150 euros).
P.S.
The SX900 has an internal Audio Recorder. After recording connect the USB stick to the computer and copy the wav files. (You can also record directly to MP3 format, but if the recording is to be edited later on the computer, it should be recorded in wav format.)
Best regards,
Chris
