mp3-wave conversion clipping

[bosey]

hi all, ive been using db for year and most happy with it... until now.

i am converting some cbr (256) mp3's to wave to play in the car but one track on the album is clipping as a result. the effect of this is quite major dropouts. I have veiwed the waveform in nero and indeed a good deal of the track is 'through the roof'.

the original mp3 is not like this and sounds fine. i have tried the 'normalise' button & also have the 'pro frequency' button checked in the config.


Any ideas? :cry:

Have you tried to convert to .wav with no DSP effects at all?

And are you converting to 16-bit, PCM wav, 44.1KHz, 2-channel stereo?

Re: mp3-wave conversion clipping

dsp effects? is this something in the power pack? i'm not aware of adding/by[assing anything like that.

all other settings as per 'cd' preset

Well if you don't know anything about the DSP effects, you probably didn't enable it; don't worry about this.

If it's at CD preset, then it would show up as 16-bit, PCM wav, 44.1KHz, 2-channel stereo.

Have you tried converting that clippy file to .m4a, .ogg, .wma or some other audio codec and then converting that file to .mp3 ?

ogg vorbis is NOT lossy. FLAC is lossless and uses the ogg container. Here's a good place to learn about audio file formats from the great Spoon himself: http://www.dbpoweramp.com/spoons-aud...de-formats.htm

As for how to convert to ogg or other formats, just download their codecs from the Codec Central Link above. Most of them are one download to be able to read and make files of that format. However, mp4 in particular requires the download of a DEcoder and an ENcoder.

Re: mp3-wave conversion clipping

Ogg isn't lossless, if you convert mp3 >> wave then dmc shouldn't increase the volume, unless there is a DSP Effect running, click the 'DSP Effects' button and make sure the left hand list is empty.

Re: mp3-wave conversion clipping

well, the fact that i was running version 1.01 explains the lack of dsp thing. so thats cleared up. i have tried all off - and tinkered with a db reduction which made some improvement, but not upto the original.

if you fancy a go i'll be happy to email it (gmail i guess) - or you can tell me to poke it; either way would be fine :smile2:

The current version of dMC is release 11 .... The earliest version I've known is release 6 , and this goes back a couple of years. I'd say you're due for an upgrade in a big way :D

Unless of course you mean release 10 which was just a little while ago.

Re: mp3-wave conversion clipping

Actually, yes, you running Release 10.1 would explain the lack of anything PowerPack related, as the PowerPack must be separately downloaded and installed into R10.1.

But anyway....
have you tried converting to a 16-bit, 44100Hz, stereo wav?
I assume your original mp3 is stereo?

Re: mp3-wave conversion clipping

ah those pesky dots have been jumping around again :teufel8: yep it was 10.

btw thanks LtData, i read thru the codec page

still haven't sorted the damn problem tho!

Does your wav clip?

Also, what does dbPowerAmp say as the frequency and bitrate of your mp3 file?
