Digital Camera and Video: HD or quality of the sound / audio? Fuji S2000HD vs.

Many buy compact digital cameras taking care of only the visual quality of video watching but not taking care of the sound.
If the "movie" HD is 720p or 1080p, then okay.
But the differences in sound quality are not poco.Ecco 2 examples:



This is a video made with the Panasonic TZ5, with a compact 8-bit mono audio and 8 khz



This video clip was shot with the next model, the Panasonic TZ7 (or ZS3) and an audio stereo Dolby 16-bit, 48 khz.

The difference is great, especially for those who love music and Concertos first case the sounds are "capped" closed, appear as heard through a heavy blanket.
In the second case, the sound is much more realistic and rich in nuances and frequencies.
MONO / STEREO = You already know: having two sources instead of one is better, as have two ears instead of one.
BIT = The depth of sound. It gives a higher resolution, just as in the photo resolution: nitide.Le things are more voices and instruments are better separated from each other, less impastati.Meglio 16-bit 8-bit, etc..
KHZ = suono.Se The frequency of attendance is limited, stamps lower will not be returned in their deep resonance and vibration and high tones will not have the purity and acutezza.Tutto will be compressed and flattened on a few frequencies, as happens with the dynamic range of levels for luminostà.Anche khz, 22 is better than 11:44 is better than 22, ecc.Il musical sampling of the CDs is 44.1 kHz.

To complete the summary, it should be noted that
- also encode and their bitrate (the volume of data in kb / sec.) have a certain weight, but the specifications are often incomplete and you have to make do with what special programs EXIF video or looking on forums and websites of the manufacturers.
- another element that can make a difference beyond the data is the presence of devices or wind noise on the microphone that the sound can lose wealth, "cork". This explains the different performance of some machines than others despite the audio data tell a different numerical cosa.In this case it is best to compare the many trials comparing video on Youtube where there is the human voice, and video in an outdoor quiet place to see if there is background noise and to what extent.
