Windows 7: How to increase Windows Sound above 100%?

Hi,

I use ffdshow audio to decode some videos and in the ffdshow settings I set the audio to increase 400%. But, some videos don't uses ffdshow and the Windows Media Player don't play mp3 above the 100%.



What application I need to increase system volume on playback? I don't want to convert the original video. The Media Player Classic have this option but the WMP don't.

What application increase the sound of system above 100%?

Windows 7 x64 Ultimate SP1/Sound Stereo 2.0/Realtek Adapter Sound

If I play movies in VLC I can crank up the sound to 400%
But the simplest solution would be to use external speakers with a build in amplifier. That way you wouldn't put too much strain on your audio chip

I don't have money for this but now I use Media Player Classic Home Cinema to reproduce all formats, including the mp3! The MPC-HC have this same option of VLC.

EDIT:

My solution: using the MPC-HC, increase the volume in 1.5dB!



Thank you!

You really shouldn't be pushing your output that hard . . as soon as you go beyond 100% you're likely to induce digital distortion, which sounds just awful really. If anyone has to put the volume output up to anywhere near 400% there's either something really wrong with the gain structure of your audio setup or the video file itself was encoded incorrectly (non-unity gain) . . I'm assuming it's the latter in this case.

At the end of the day it's going to be easier to fix the video files than to keep trying to adjust for them . . you can adjust the audio file in the container without affecting the video stream which is great, a single batch process on all the offending files would fix the problem.

IF it's ALL video files then I'd basically do what SledgeDG suggested . . I'd set your media program's volume output at 100%, set windows' volume output at about 90% (most op-amps in consumer audio devices can't handle transients beyond about -5dB) and just turn up the volume on your amp/speakers . .

What amp/speakers are you using by the way?

In speaker enhancements, check Loudness Equalization to boost the volume.

Mp3s that are encoded too low can be fixed with this one in seconds without the loss of quality (since there is no new encoding required)

MP3Gain
or what I used to use:

Video streams you would have to demux, work with the audio track and remux it again

Thank you for reply!

In my case, the increase is very low: only +1.5dB in the Media Player Classic settings! My ears do not perceive any digital distortion, only the increase of volume!

I didn't perceive any difference in my mp3 files!

I use the MP3Gain only for the musics in my MP3 Player.
