make clang happy

Audio stream does not have the same sample count, so a history of N does not mean the same time regarding stream. Let process packets of 512 samples per history slot

We need to clamp the noise in fact. But it is better to use the peakMax value since once the limit has been reache, it will not be cleared

A bit more simple

Take care that smooth value can now be changed to 0 if packets are bigger than 512 - to make it a bit more precise, let's use the ramp time

Let's take care of the current position to not mess the peak history

There is no need of the gain history unless for debug. Let save some RAM and make the code a bit easier

curGain must be called lastGain since it is used to record the last gain applied

Number of sample per video can be different between two different files, so smooth will not have the same duration. Let's normalize on 512 elements audio packets

Let's initialize curGain asap

Remove the noise clamping, each movie has its own noise level. Just be sure that we do not amplify too much the noise

50 is bit too high for noise limit, let use 20

Do not override the maxPeak of the current packet with the max peak of the full stream. The gol here is to compute the gain for the current packet

Smooth can also be null, it means no smooth and direct volume change

6ed20122d6e236b35d116a9996244c063c0f1aed authored about 10 years ago

Target can be null, it just means that gain will always be clipped to one

Sound track always start with white noise, do not amplify the noise

MaxGain of 0 is now supported since it is now relative

A bit more helpful help

Let's clip the max gain before the smooth because smoothing

Save the gain applied for the maximum peak. Use this as a reference for the max delta gain accepted

When the new buffer is smaller, the buffer is totally cleared unless it is specified - It is the case for peak, we want to keep peak history
