Audacity Forum

Hello, my name is Marta and I just started using audacity (1.2.6. stable) to record and edit audio.

I have a following issue: when I record, it sounds all great, there is no clipping at any point. I export it to an MP3, sounds great. I make a little movie out of it, post in on you tube - and then, when I play it back, if I crank the audio up, the passages with the loud high pitch singing give the 'whistling' noise on my laptop, as if they were to blow up my speakers. Is there any way I can edit the original file so that after conversion this will not occur? Can that be the question of just my poor-quality laptop speakers?

I posted this little video on you tube (http://www.youtube.com/watch?v=LweF8xkUbg4), the problem occurs mainly in these moments: 1minute 6 seconds, 1 minute 31 seconds, besides in two more spots. I know maybe it doesn't sound too bad but it irritates me - and the original didn't have this problem.

I tried to search the forum for similar issues but I don't know the technical vocabulary well enough, probably that's why I didn't find it.

Thank you.

Best, Marta.

What a terrific cut. I love the film effect over the faded rose. Excellent.

On a weapon's grade sound system, the high notes are waaaaay to crisp and they are distorting the compression systems. On a couple of notes, my wine glass started to vibrate and sing.

What happens if you send the video with uncompressed WAV sound instead of MP3. It sounds like it could be the MP3 and the YouTube sound compressors fighting with each other. Or there could be three compressors. What kind of movie did you send?

Find yourself a good pair of headphones. You can't mix to "computer speakers." I didn't ask, but are you a young woman with super hearing? If you can't hear the crispness going up to YouTube, then YouTube will destroy your show.


Now it's the right-brain's turn. You can apply the equalizer effect and roll off the high notes around 7KHz or so. Apply film noise, pops and clicks before you do that and it will sound like your voice is on the film. Film that old had optical sound and it wasn't very high quality or crisp.

If you play your video via Youtube at the higher YouTube quality setting (480p rather than 360p) the weird sound effect on the high frequencies , (caused by compression artifacts), does not occur.

BTW IMO your recording could benefit from dynamic range compression, (the difference in volume between the loud and quiet bits is too great),

Oh I can hear your computer's hard drive clicking in the background, you should put the mic further from the computer.
