[Csnd] Volume of output WAV file

Subject	[Csnd] Volume of output WAV file
	Hi everyone, This is probably a very simple question. I've output a Csound composition to a WAV file. However, the volume of the file is too low. I'd like to boost the overall volume. However, when I boost the amplitude levels in the CSD file and run it, I see this report: overall amps: 1.20914 1.44500 overall samples out of range: 26 842 I've always taken this to mean that there has been some distortion in the output and that this should be avoided. Is that correct, or do I not need to be very concerned about samples being out of range? If I do need to keep the amps under 1.00, then how do I boost the overall volume of a track? Is that something I'd have to do outside of Csound? Thanks for any guidance you can give!

	You're right, some of your samples are clipping. Rather than try to do this in Csound I would simply normalise the file afterwards with an audio editor.

	That's exactly what I do (I usually use Audacity to normalize to -3dB or -4dB). On Wed, Oct 21, 2020 at 10:55 AM Rory Walsh <rorywalsh@ear.ie> wrote: You're right, some of your samples are clipping.

	Try adding a low pass filter too, before the output.

	Also, to match the continuous perceived loudness of pop music, you likely need to adopt their techniques. This is a whole artform but in csound terms it largely involves bandpass filters and dynamic range compression. It's a place on the border of arrangement, composition, studio techniques, and mastering. It's ubiquitous in broadcast music but IMHO it's highly constrained and unnatural.

	A few samplesout of range usuall isOK IMO. What I sometimes do is render to floaing point and then iuse thescale utiliy funtion to set a maxium value. that can even be done as a script otr Makegile option. ==Jon ff On Wed, 21 Oct 2020, Jason Hallen wrote: > Hi everyone, > This is probably a very simple question.

	This was a great discussion. Thanks to you all for sharing your approaches to this issue! I was able to normalize the WAV file in a DAW. It helped boost the volume.
