Re: Additional *float-format* options

Nice find Edgar. I've seen the ".n" somewhere before (and used it myself) but the "#" and "+" option are new to me. Tested on Ubuntu 10.10 with Audacity 1.3.12 and 1.3.13 Tested on Windows with Audacity 1.2.6 , 1.3.7 and 1.3.12 All work as expected. Test script (setq x ...

Re: Analysis of files

You can find the Hz from "Analyze > Plot Spectrum". This also has an Export feature that allows the numerical data to be exported as a text file. I thought the 'Wave Stats' plug-in already provided the mean dB (RMS) value. In Audacity 1.3.12 there is a certain amount of customisation of th...

Re: Windows Media Player and ".au" project blocks

As waxcylinder has said, you should not mess with the .AU files in the _data folder. They are not ordinary audio files, they are Au dacity data files that are used in the Audacity Project. If any of these data files are manually changed in any way there is a high probability that the entire project ...

Re: 1.2.6 noise removal superior to 1.3.6 ??

I do not use AGC while recording. Like I posted previously (in this thread), I use AGC as the final (or - as in the case of Dark Side of the Moon - as posted previously in this thread - penultimate) step in preparing wav files before mp3 encoding or video soundtracks before processing. Anyway, that...

Re: Cant select 'stereo mix' in the right with EMU 0202

On XP, to record sounds playing on your computer using the EMU 0202 you will need to use a "loopback connector". A loopback connector is simply an audio lead (with appropriate plugs) that you use to connect the line output of the 0202 to the line input of the 0202. I realise that this is a...

Re: Recording Volume Problems

I assume that there is no volume control on your guitar? If there is no way to lower the volume on the guitar, or lower the gain on the lightsnake, you could work round the problem using a foot pedal such as a "Graphic Eq". As well as having multiple Eq bands, Graphic Eq pedals usually als...
