Boosting audio on PSP video

[onihR]

Hi eveyone.

Please forgive me as I am very new to this, so any help would be appreciated.

I have recently purchased a 2GB memory stick for my PSP, and now enjoying movies on the go.

The question I have for everyone is this....how do I increase the audio volume in the encoded file.

I catch a train to work most mornings and have trouble hearing the audio of a converted file.

The software I use are:
Step 1: DVD decripter
Step 2: PSP Video 9

I would appreciate any help regarding this.

welcome to the forum

IIRC PSP video 9 is capable of normalization, should boost volume to the levels you need

for boosting volume in an already encoded file, demux streams with YAMB, apply gain with aacgain (or re-encode with behappy, belight etc) and mux back to mp4
