Dear all i?m working with a program i?ve made in R (using functions that others created) to run my program i need a sample. if i generate the sample using for example, rnorm(n, mu, sigma) i have no problem but if i obtain a sample from a column in excel and i copy it, the program says that there is a mistake: it says "Error en `[.data.frame`(data, indices) : undefined columns

I was wondering when it would be useful to compress very short audio files. The answer may be when there are lots of files, for instance in the case of sound fonts, or a large collection of transients. Probably it would be better to compress the whole collection as a single large file obtained by juxtaposing the short clips, with cues or marks to separate the original files. May be this

I'm working in Rosario, Argentina, trying to plot some contours. I found the function "draw.contour" created by James Forester at R-bloggers. If you take a look at that function you'll see it's very useful! But I have a problem with it and James is trying to help me (but also asked me to seek for more help) I hope you can help me (don't worry if you can't): Using

Dear all, I've converted a wav file to flac but during the process three wrnings were casted. One of them I recall, it said that a BEXT chunk is unrecognized and thus ignored. Wouldn't it be posible to keep the unrecognized information as is when decoding the file? In general the extra chunks are located before or after the audio content, and represents a tiny part of the whole

Dear All, I've sent yesterday this issue, but as it contained two screenshots, I'm not sure if it reached the list. I post it again with some updates. 1) I had encoded a WAV file three years ago. Examining the FLAC file with an HEX/text viewer, i find at the beginning, after some headers, it declares reference libFLAC 1.3.1 20141125. However, I'm pretty sure I didn't use that

Dear Friends, I am new to this mailing list. I am with the National University of Rosario, Argentina, and I am writing a book on software-based acoustical measurements, which includes a chapter on FLAC for archival and streaming purposes from an remote embedded system including a sensor. I would like to ask why the seekpoint information in the seek table metadata block reserves 64 bit for

Dear all, I have a wav file that when I try to encode with the FLAC Frontend, I get "ERROR: unsupported format type 3". When I open it with an audio editor I find it is 44100 / 32 bit. I requantized it to 16 bit using the default dither and then compressed it with FLAC to get a 61 Mbyte file (the original was about 347 Mbyte). Obviously, this altered somewhat the quality, although
