Sorry, i've forgotten one word in my sentence and the parameters were not defined.
So, here is the complete schematic for the motor force (BL) understanding IMHO.

Is this project dead?
You'll need to put C:\Output in the Output path>Specify folder.

For the name format, you can use...

Code: [Select]

If it was just one folder deep for all files, you could use

Code: [Select]

but I thought that was probably unlikely??

Time to update your signature, delete all your vinyl rips and throw away your 32/384 ADC greynol. You need to buy a Zoom and rip your vinyls with the built-in mic. :))  :))  :))
General Audio / Re: Linux Audio Conversion Script Terminal Based
Last post by abajaj11 -
At the moment i'm using a mish mash of messy audio conversion scripts (found on github) to convert audio into different formats. I have a master FLAC collection and convert into different formats for different devices, ie. mp3, opus, ogg, aac  etc. My requirements are to keep the exact same directory structure, id tags, etc as the master collection and output them into required format. Does anybody know of a single script / tool what can do this what is terminal based and works on linux?
I wrote this for use on my linux mint box. Works great. Converts my entire flac tree to mp3. I have a similar one for wav, though anyone should be able to modify this one to do wav.
    if [ -z $1 ];then echo Give target directory such as . ; exit 0;fi
    find "$1" -depth -name '*' | while read file ; do
    directory=$(dirname "$file")
    oldfilename=$(basename "$file")
    newfilename=$(basename "${file%.[Ff][Ll][Aa][Cc]}")
    if [ "$oldfilename" != "$newfilename" ]; then
    ffmpeg -i "$directory/$oldfilename" -ab 320k "$directory/$newfilename.mp3" </dev/null
    rm "$directory/$oldfilename"
    #replace all flac occurences with mp3 within filenames
    find . -depth -name '*flac*' -execdir bash -c 'for f; do mv -i "$f" "${f//flac/mp3}"; done' bash {} +
    # replace flac with mp3 WITHIN all .m3u files
    find . -name "*.m3u" -exec sed -i 's/flac/mp3/g' {} +
Thank you for all these replies. I will go over and answer these soon enough. To quickly answer one question: In order to upload to Bandcamp you must use FLAC, WAV, or AIFF and it must be under 291MB. For my math calculation, this is the formula: Length of time in seconds(x) = 291. For example, 3600x = 291. I would divide the left side by 3600 and the right side by the same. This would result in X = 0.08083. I then take this number and convert it to kiloBytes, not bits. The results is 80.83, but I just round down to 80 and boom! I could convert this file at a bitrate of 80 KB/s. This works really accurately with fre:ac but Format Factory is meh. I'm trying to figure out a way to result in more listen-able file concerning volume at the source recording level.

Some security software is preventing the C# compiler to generate the XML serialisation assembly for CTDB.
Apparently the serialization assembly can be pre-compiled and distributed with the application, but the process is a bit complicated.
I've tried to do it, but i'm not entirely sure if it's going to work. Can you try this for me? Just unpack the archive into EAC folder.
Hi. Sorry if this is addressed elsewhere, but I've looked and can't find the answer.

I have a directory that reads as follows:


I am converting, and I have an /Output folder, and the default is taking all of the files in the subdirectories and putting them all into the /Output folder, all of them. This is not what I want.

What I want is the converted files to go into a directory structure just like existed before. So that I have:


and so on.

What settings do I do for that?

Audio Hardware / Re: Which RCA input to use, 700mv or 900mv?
Last post by Arnold B. Krueger -

I recently got a new pair of active speakers (S1000DB), and I'm using both analog (PC) as well as optical (TV). The speakers have two analog inputs, however. One RCA pair is "700mv" and is labeled "AUX", the other is "900mv" and is labeled "PC." My analog source is a PC with a Xonar D1 sound card. I'm not sure which RCA pair to use to connect the 3.5mm line out from the Xonar to the speakers. I would assume I should connect it to the "PC" RCA pair, since the source is a PC, but this produces a quieter signal than the "AUX" and optical inputs.

The specs of the Xonar say:

Output/Input Full-Scale Voltage, 2 Vrms (5.65 Vp-p)

But I don't know what that means...  :-\

What I can say for sure, however, is that when I connect the optical out of the Xonar to the speakers at the same time as the analog out and switch between the sources, the 900mv PC connector is much quieter compared to the 700mv AUX connector. The 700mv AUX connector is in fact exactly as loud as the optical connector, which (perhaps naively?) makes me believe that's what should be used here, even though the source is a PC sound card.

Does someone know which is the correct RCA pair to use here?

The full specs of the sound card are listed here:

The difference between 700 mv sensitivity and 900 mv sensitivity is about 2 dB which is rarely enough to make a significant difference. The one with the higher voltage is going to be little louder all things considered, but you may not be able to reliably hear the difference with rapidly varying audio signals like music. You should be able to use them interchangeably
The Zoom recorder has a 1/8" input for line signals. Although the preamp has RCA output jacks, they are obviously taking the signal outside of the differential domain. One of the advantages of running differential circuits is lower noise. My concern was thus increased noise in doing a direct connection since I would be loosing the differential operation, plus it was a hassle to pull the FocusRite from the studio. So I set up the Zoom. This particular preamp is about 25 years old, being one of the first MP-1s built and so is a little nosier than later units. The Zoom was simply placed on a table, but what I didn't think about is that there is an arch between the living room where the speakers reside and the table. Imaging detail is diffused by both the arch and the flat plane of the table forward of the microphones in the Zoom.

There is a hum in the recording- the hum comes from the furnace fan. Having lived in Minnesota (which gets cold) and the same house since 1971 I no longer think about it.

I was asked to record a quieter portion of the LP. The first cut is a good 6 db louder through most of the track. I did prove my point despite the usual remonstrations.

Any possible losses due to taking the signal outside of the differential domain vanish in comparison to losses inherent in taking it outside of the electrical domain and into the acoustic domain.

Look at it this way - the designer of your preamp obviously designed the recording output jacks for the purpose of driving a recorder, which is the task at hand.

If you have so little respect for the preamp's designer's implementation of recording outputs, what are you doing with the rest of such a piece of junk in your system?
