How does audio clipping affect my track? (sound quality vs volume)

Before you all hate on me for posting a nooby question, im asking this because when i record and upload mixes to soundcloud, in concerned that my mixes full volume wont be that loud, especially if people are listening to it through low power audio players (mobile phones) or complain cause they have to turn their speakers up lol. Maybe im overthinking this but id like someone elses opinion.

But my general question is, what exactly does the red cap on the main output mean?

I know i can turn down my master volume and turn up my speakers to stop the clipping red line, but i cant see any difference in the sound quality comparing 'non-clipping' and 'clipping' apart from the fact the low volume does annoy me.

Please post ur opinions! :)

clipping is bad full stop. the headroom in traktor and the audio 8 is good enough so you shouldnt be able to do major damage to anything.

essentially when ur clipping an audio signal, ur asking the speaker to do the impossible and get to a position its not designed to. instead of having a nice smooth shape to follow from each end of its movement range, when you clip the audio your pushing the speaker beyond its range of movement which will result in a blown speaker. the other interpretation is that the speaker has to change direction extremely quickly compared to when its following a nice smooth waveform.

one way to look at it is if you have a close look at your waveforms in traktor...thats exactly how the speaker moves to produce the sound

Record a track on Traktor and clip it, then play it back on a system. You'll get why Chris says it's bad.

thats the thing, i tried recording a short mix with clipping and my speakers down
tried the same thing with my levels right and my speakers higher
pretty sure i cant see much of a difference.... i think
im using logitech z2300 speakers too, they have some pretty powerful grunt!

thanks for ur response chris! :)

i should definitely take this into consideration, i would never do it live cause i can just adjust the speaker levels
also im just using my laptop soundcard output, looking into investing in a audio 2 dj pretty soon hopefully

You can't really hear a little bit of clipping because its only a couple of the least significant bits being truncated. More clipping = more bits dropping off = more distortion. On bigger systems it will take less to notice, but if you push it enough you can hear it very plainly even on earbuds. Also an A2 will be able to go MUCH louder than a typical laptop soundcard, so that will definitely help you out.

If you're concerned about volume why don't you just raise the volume post mix in something like audacity? you can set it so that it will raise to the max volume possible without clipping.

Nothing wrong with Z2300's but PA 'grunt' is a different animal - which is why the speaker(s) can 'blow'. As DD says, an external soundcard will significantly change all that. In the meantime, get the ASIO driver for your laptop. (It's the recommended driver for the A2 as well).

so does that speed up the music?

that is a damn good idea...
lol i think i might have had the impression audacity would clip too, nvm

solves everything haha thanks!

that brings me to a different issue which ive asked before but i didnt get a full response: http://www.djtechtools.com/forum/showthread.php?t=34015

im actually using my samsung lcd monitor as my main output (through hdmi)
which goes to my speakers. i still cant setup my cue headphone output because i still cant get asio4all v2 to work.
when i used virtual dj, i was able to choose 2 soundcards and output mains to hdmi and headphones to my laptop 3.5mm. cant figure out how to get traktor 2 going since it has no option for 2 separate sound cards and asio4all doesnt seem to like me ;|

audacity has the ability to "show clipping" in the menu

you can amp a song that has no clipping in audacity to the point it clips. the best suggestion would be get good at working your transitions to prevent clipping, stay within 0/1 red on the mixer (depending on the mixer eh), and then review in audacity to see where you borked it. rinse, repeat, practice.

edit: dont do this
