![]() ![]() Its basis is in the fact that audio formats have a fixed decibel range, e.g. This is a legitimate technique that's unfortunately been abused in the past couple decades by music producers engaged in the loudness wars in the quest of producing a "louder" sound. You can get less of a boost this way, but it will usually sound better. You can also use an equalizer setting that accentuates certain frequencies to the max while toning down other frequencies.You end up with a pretty flat frequency response and less-than-high-quality audio, but it increase the loudness of the audio channel compared to more reasonable/suitable equalizer settings. The most basic way of doing this is cranking each frequency range's amplitude all the way up.Adjusting the levels of the audio channel, much like an equalizer (a set of volume knobs for different frequencies that adjust the amplitude of that frequency(range)):.So from the perspective of a software audio amplifier, all you can do is manipulate the sound channel to increase the perceptual or relative loudness of the audio channel within the fixed range determined by your hardware. VLC Media player, FFdshow, or any other audio filters are unable to change this fact Therefore, along its output range of frequencies, it can only achieve X decibels of output no matter what input it receives. That decibel range is determined by the hardware specs of your speakers and the volume settings. So your speakers are already preset to output a particular decibel range in response to audio channel data. Instead, what is being amplified are the digital channels in the your audio stream. There's no actual electroncal/analog signal to be amplified. Software amplifiers don't work the way that electronic amplifiers do. So I don't think there's a way for an application program to increase the wattage the internal amplifier draws and then cause your speakers to break.Īlthough come to think of it, they do have "pre-amps" to bring things to "line level." but I'd have to defer to an audio expert on that. On a laptop, they've included "powered speakers" for you, so to speak. Sound cards don't contain amplifiers - that's why you have use powered speakers with them. I can see some really cheap or low quality laptops possibly being susceptible to defects here, but it's pretty unlikely. In a laptop, the internal amplifier has been selected by the manufacturer and should always work with those speakers which are also manufacturer selected. So if you use a 100W stereo with speakers rated 20W, you can blow them. You should not be able to hurt your speakers unless you are using an amplifier that is rated above what the speakers are. ![]() I believe the only thing that will happen when you raise the volume above 100% is that you will get clipped, distorted audio. ![]()
