I would like to know the needs for amplification I have use amplification and equalization.
Some of my records are very low and I have recently constate that with some amplification and a litle equalization intensifing high frequencies make the sound more frontal with some loss on ambience. My records are MS stereo the majority.

Hello FREITOJOS,

There are two types of amplification "effects".
1) gain increase
2) Amp simulation

1) gain increase can be done on a sound editor. Some DAWs have a built-in effect that can do a simple gain increase.
This has the effect of increase the volume of the signal, but also the volume of any noise present in the recording.

2) Amp simulators can also increase gain, but the main intention of using an amp simultion VST is to introduce to the sound the coloration associated with some amps. These will usually have non-linear responses and produce "soft clipping" or "overdrive" of the signal when pushed.
This type of amp simulator VST is usually intended to be used on guitars and for normal purposes needs to be followed by a cabinet simulator (which simulates the speaker cabinet). Some amp sims have a cabinet built in, others require an external one.

Now, I believe none of the above really solves your problem. For two reasons:
First, a low level signal may also contain s relatively strong noise signal. Amplification by effects will bring both signal and noise up and will normally result in a sound that contains too much noise to be usable.

Worse, if the sound is recorded and digitized at low level, only the lowest bits of the digital audio get used, with most bits being empty.
So essentially, although the sound was recorded as, say, 16 bits since the signal is too loaw and most of the bits are not used the result is that effectively the signal would perdorm as if it was say 8 bits. Amplidication of this signal by digital means will introduce artifacts due to the low bit depth.

I might be wrong, and an effect may indeed solve your problem. Have a look at www.kvraudio.com and search for amp effects. Download a couple of free ones and try them out.
If that does not help you will need to boost your signal before it gets digitized. This could mean a better mic, a better sound card with a built in pre-amp or an external pre-amp.
