Audio - Link Microphone and playback into one device?

Is it possible to merge two audiosources togeather in any nifty way?
Mainly interested in the default recording device (or otherwise specified) with the playback device.
I'm using JACK which i thought was able to do so but never got it working in any practical way al tho i enjoy playing around with it.
Why i want to do it is because i want ffmpeg to easily pick up two sources from one channel, and being able to switch around in say JACK would be awesome in real time not affecting the ffmpeg stream, considering i might be streaming something for a bit and want to switch audio source mid-stream to erm i dunno say a radiostation while i go off doing something else.
Linux is versatile so i bet it's possible, i just don't know how yet

I've got this partially solved:
#!/bin/bash
KEY=`cat key.db`
ffmpeg \
-i http://pub1.di.fm:80/di_vocaltrance \
-f alsa -ac 2 -i hw:0 -acodec mp3 -aq 1 -ab 128k \
-f x11grab -s 1920x1080 -r 25 -i :0.0 \
-c:v libx264 -preset fast -pix_fmt yuv420p -s 1280x800 \
-c:a mp3 -ab 96k -ar 22050 \
-threads 0 \
-map 0:0 -map 1:0 -map 2:0 \
-f flv "rtmp://live.twitch.tv/app/$KEY"
But now for the tricky part..
Everything sounds like i'm inside a tin-can for some reason (probably to do with the mixing, ffmpeg probably don't like that for the format?).
So i thought i'd give ffmpeg-full a go with jack support.
Giving me the option to link several inputs into one single channel making it a single-audio track in the video, also giving me the option to patch this by muxers and what not.. But it gives me this:
-f alsa -ac 2 -i jack \
Produces:
[alsa @ 0x1399280] cannot set sample format 0x10000 2 (Invalid argument) jack: Input/output error

I travel - a lot. I have apple accounts in Canada, US and Brazil. I want to consolidate and listen to my music and movies on one device. Right now there is a 90 day limit per account on each device. How can I download and use all my purchases?

There must be a way for people who live in several countries or speak several languages to purchase music and movies in various national Apple IDs and then consolidate and listen to the media they own on just one device. How can I do that?

There must be a way to get all the music and movies into one place. Maybe on Laptop rather than iPhone or iPad. I can get one set to one ID and the other to another, then switch to the third ID since I have not changed the two in 90 days. But I would need to download all media during the time each device is on each ID. Must be possible, but I don't know how.

Can I sync the songs from two different Apple IDs (HK and JP) into one iPhone?

I want to buy some songs from a HK Apple ID and a JP Apple ID.
I just hope the songs of two Apple ID can appear in one iPhone.
But I don't want can I sync the songs from two different Apple IDs (HK and JP) into one iPhone.

Are you currently in Japan or Hong Kong ? You have to be in a country (and have a billing address in that country on your account) to buy or download from its store, that is included in the store's terms.
You can sync content from different accounts from your computer's iTunes library.

I have one apple account and one apple ID. I have several devices under that ID. Why when I download and app on one device it goes on all devices?

I have qualitynet either wired internet. I buy a card good for a month at a time, I can only log into one device at any one time. Are there settings I can adjust on my airport express to allow all my devices to connect to wi-fi without having to log out.

I have qualitynet either wired internet. I buy a card good for a month at a time, I can only log into one device at any one time. Are there settings I can adjust on my airport express to allow all my devices to connect to wi-fi without having to log out of one devise before using another?

Some Internet providers that limit access to a single device at a time do so by the device's hardware MAC address. If your ISP is one of those, you may be able to substitute the MAC address of your AirPort Express base station for the computer. I would suggest that you contact them to find out if this is allowable.

What's the easiest way to select all my files from all the folders on a hard drive and place into one folder?

Hi there,
I have about 30,000 images all in hundreds of folders. I'm wondering what the easiest way to get them all into one folder so I can select and convert them all from .psd, .tiff, etc all to jpg. The reason I'm doing this is because the folder structure is such a mess, that I'm just going to import them all into aperture to sort everything. But the .tiffs and .psds are 100 mb each so I want to scale them to jpgs that are only 4 or 5 mb before I even think about importing them into aperture.
I tried doing a search for "kind is image" and it shows them all but a ton of them are renamed the same thing so when I try to select all and move into one folder it tells me I can skip that one or stop copying.
Any thoughts or ideas on this?
Thanks,
Caleb

Hi russelldav,
one note on your data handling:
When each of the 50 participants send the same 60 "words" you don't need 3000 global variables to store them!
You can reorganize those data into a cluster for each participant, and using an array of cluster to keep all the data in one "block".
You can initialize this array at the start of the program for the max number of participants, no need to (dynamically) add or delete elements from this array...
Edited:
When all "words" have the same representation (I16 ?) you can make a 2D array instead of an array of cluster...

I would like to get only specific channels from several .csv files and concatenate into one group.

Hello,
I am working with other groups and getting the data in daily .csv files. When I use the "concatenate groups" script along with a script on importing files, I end up getting a huge file that takes about an hour to concatenate. In order to reduce the amount of time and memory that this takes, I was hoping that someone could help me modify the script so that I could just list the channel name that I am interested in and concatinating only those channels rather than all of them.
For example, if voltage, temperature, pressure and time data are taken daily for 30 days, I would like to import only the temperature and time data (from .csv format) and concatenate into one group.
I have attached the .vbs files that I use.
Thanks in advance,
Alan

Hi Alan,
Actually, the feature you're asking for is already in the code of mine that you sent back. Look on line 11 of the main VBScript: ChannelSet = "" ' "" or "1-" (DataPlugin) or "Sheet1" (EXCEL Wizard)
If this "ChannelSet" parameter is set to something other than "" or "1-" then it is used in line 78:
Call DataFileLoadSel(FilePaths(i), DataPlugin, ChannelSet)
Yo can specify the channel indices to load with an expression like this:
ChannelSet = "[1]/[1],[3]"
Let me know if you have further questions,

How to join fields from different internal tables and display into one int

hai i have one doubt...
how to join fields from different internal tables and display into one internal table..
if anybody know the ans for this qus tell me......

hii
you can read data as per condition and then can join in one internal table using READ and APPEND statement..refer to following code.
SELECT bwkey                         " Valuation Area
         bukrs                         " Company Code
    FROM t001k
    INTO TABLE i_t001k
   WHERE bukrs IN s_bukrs.
IF sy-subrc EQ 0.
    SELECT bwkey                       " Valuation Area
           werks                       " Plant
      FROM t001w
      INTO TABLE i_t001w
       FOR ALL ENTRIES IN i_t001k
     WHERE bwkey = i_t001k-bwkey
       AND werks IN s_werks.
    IF sy-subrc EQ 0.
      LOOP AT i_output INTO wa_output.
        READ TABLE i_t001w INTO wa_t001w WITH KEY werks = wa_output-werks.
        READ TABLE i_t001k INTO wa_t001k WITH KEY bwkey = wa_t001w-bwkey.
        wa_output-bukrs = wa_t001k-bukrs.
        MODIFY i_output FROM wa_output.
        CLEAR wa_output.
      ENDLOOP.                         " LOOP AT i_output
    ENDIF.                             " IF sy-subrc EQ 0

SQL*Loader - How to combine Flat File 3 columns and put into one single column

Receive a flat file delimited by comma. Want to combine Flat File last 3 columns and put into one single column(Table).
e.g.
Flat File
100,239,30,20,30
While inserting into table want to combine last 3 columns and insert into invoice number column.
302030

It is not possible to combine the last 3 columns as those columns are seperated by commas and in the SQL Loader control file you must ve specified COMMA as an delimiter. So u better have all the columns in the table plus add one more column which holds the concatenation of the 3 columns.

Is There a Program that can compress tracks and Cds into one long tra

I have a couple long audio books and I would like to have it all in one track.

DSmith: I use?Easy CD-DA Extractor which is shareware, but you simply tick a box to turn all that you rip into one track. This can be the entire CD, or specific tracks that you pick.

Capture audio with microphone and save to disk

Hello,
I would like to know if there is any way to record audio from
user's output? Let's say I capture it using its microphone, and I
want to create an audio file with it, or a swf file or whatever
file it is. I need to save that audio for further playback. Can
someone point me in any direction!? I have been surfing on this
topic but I didn't find anything, apparently it can't be done, but
I would love otherwise.
Thank you,
JCA

Yes that's the way it could work. FMS is designed for
streaming audio, video and data around keeping things synchronised
in real time, but it can save the streams to be played back later
as well.
It would be an expensive solution if that's all you want to
do.... there is an open source 'version' in development... called
red5, but I think you need to know how to program in java, although
I'm not sure.
Or you could look at adobe connect/formerly macromedia breeze
- It prebuilt and is a pay for use service, but does much more than
what you're looking for. I'm pretty sure you can custom logo it
etc. You might want to try the free trial account and check it

Fetch data from two tables and insert into one table

I have similar to the following data in two tables (@Plant, @PlantDirector) and need to consolidate into one table (@PlantNew) as follows.
DECLARE @Plant TABLE (PlantID INT, PlantName VARCHAR(100))
INSERT INTO @Plant (PlantID, PlantName) VALUES (1, 'Name One'),(2, 'Name Two'),(3, 'Name Three'),(4, 'Name Four'),(5, 'Name Five'),(6, 'Name Six')
Director data for the Plants exist in the following table. Assistant value 1 means Assistant Director and 0 means Director.
Data exists only for subset of plants and a Plant may have one or both roles.
DECLARE @PlantDirector TABLE (PlantID INT, PlantDirectorID INT, Assistant bit)
INSERT INTO @PlantDirector (PlantID, PlantDirectorID, Assistant) VALUES (2, 111, 1),(2, 222, 0),(4, 333, 0),(6,444,1)
The above data needs to be inserted into one table (@PlantNew) as follows:
PlantID in @Plant table is IDENTITY value and needs to be inserted as-is into this table.
PlantDirExists will get a value of 1 if at least one record exists in @PlantDirector table for a PlantID. PlantAssistantDirID and PlantDirID should be set to the corresponding PlantDirID or NULL appropriately depending on the data.
DECLARE @PlantNew TABLE (PlantID INT, PlantName VARCHAR(100), PlantDirExists bit, PlantAssistantDirID INT, PlantDirID INT)
INSERT INTO @PlantNew (PlantID, PlantName, PlantDirExists, PlantAssistantDirID, PlantDirID)
VALUES (1, 'Name One', 0, NULL, NULL),(2, 'Name Two', 1, 111, 222),(3, 'Name Three', 0, NULL, NULL),(4, 'Name Four', 1, NULL, 333),(5, 'Name Five', 0, NULL, NULL),(6, 'Name Six',1, 444, NULL)
How do I achieve the above using SQL ? Thanks.

like this
INSERT @PlantNew (PlantID, PlantName, PlantDirExists, PlantAssistantDirID, PlantDirID)
SELECT p.PlantID,
p.PlantName,
CASE WHEN pd.PlantID IS NULL THEN 0 ELSE 1 END,
PlantAssistantDirID,
PlantDirID
FROM @Plant p
LEFT JOIN (SELECT PlantID,
MAX(CASE WHEN Assistant = 1 THEN PlantDirectorID END) AS PlantAssistantDirID,
MAX(CASE WHEN Assistant = 0 THEN PlantDirectorID END) AS PlantDirID
@PlantDirector
GROUP BY PlantID)pd
ON pd.PlantID = p.PlantID
Please Mark This As Answer if it helps to solve the issue Visakh ---------------------------- http://visakhm.blogspot.com/ https://www.facebook.com/VmBlogs
You're missing a FROM
insert into @PlantNew
SELECT p.PlantID,
p.PlantName,
CASE WHEN pd.PlantID IS NULL THEN 0 ELSE 1 END,
PlantAssistantDirID,
PlantDirID
FROM @Plant p
LEFT JOIN (SELECT PlantID,
MAX(CASE WHEN Assistant = 1 THEN PlantDirectorID END) AS PlantAssistantDirID,
MAX(CASE WHEN Assistant = 0 THEN PlantDirectorID END) AS PlantDirID
from @PlantDirector
GROUP BY PlantID)pd
ON pd.PlantID = p.PlantID
