Analogue line input on SB Live!

Hi,
I am trying to sample my old vinyl record collection using my Sound Blaster Li've! PCI (think that was the model - it was the original (not Value) version of the card with the seperate header for the coaxial digital and MIDI I/O).
Unfortunately, I get severe clipping regardless of the recording volume on the Volume Control panel. I know that my photo pre-amp is capable of high voltage outputs and therefore wondered if anyone was aware of the sensitivity of the analogue line input in volts of this particular model?
Many thanks.
Regards,
Paul.

If your pre-amp is a phono pre-amp (with RIAA in-build), I suppose it's not the culprit for clipping.
How have you set the recording and source (input) levels on Volume Control and Recording Control?
Try adjust the recording level by the 'hights' (loudest outputs) of the record (you know those recordings so you can easily find those places (or you can look on vinyls surface where the darkest areas are --> loudest outputs)).

Clipping problems using SPDIF input on SB Live

.Clipping problems using SPDIF input on SB Li've?Hello everyone
I'm new to this community and I'm banking on someone being able to help me!
I'm connecting a DAT player to the SPDIF input on my Soundblaster Li've card and recording using Audacity.
Within Creative Audio HQ I've got the SPDIF volume level set to 00% (for starters, perhaps someone can explain why there is a volume control when I thought this signal was staying in the digital realm?!) and when I record in Audacity the resulting material clips with high transient sound... a piano, for example, distorts on the louder notes.
I need to take the level down to about 70% (or the equivalent in Audacity would be 0.7 - the 2 'volume' controls are connected) to avoid any clipping.
I've had the sound card years and used to use SoundForge without any problems. Any ideas why this is happening in Audacity?
I'm using XP and?I have downloaded the latest drivers and turned off the MOBO onboard sound in my BIOS.
I would be grateful for any assistance anyone can give.
Best Wishes
Steve

Line input question

I would like to be able to use my desktop speakers to listen to a satelitte radio receiver using the Mac Pro's line input and volume controls but I can not find a way to nake this audio "pass through" from the line input to the line output.
I know that there is analog audio present at the mini plug I am feeding the line input with because I can select it as my recording source in other applications (garage band, peak, etc.). Obviously, I would prefer not to have to run one of those applications to monitor the audio.
Any suggestions are appreciated.

Thanks for your input, but I was hoping to find a solution that did not involve more hardware. I would really be quiet happy if the audio was just able to pass thru.

Installed Camtasia which wanted Soundflower and now line-input doesn't work

I installed the Camtasia demo which asked to install Soundflower to get the audio recording working, then I went to skype and my mic/headset (attached to the line-input) no longer worked. I've tried attaching different headsets to the same input, visiting System Preferences / Sound and tapping the mic, but nothing seems to fix it, and I haven't installed anything else, so it has to be Soundflower doing something to affect the line-input.
Has anyone else noticed this? Is there any easy fix?

Thanks, I've tried that but they haven't responded yet. I wondered if anyone on the apple forums had seen a similar problem...

1DC- Sound Recording via Line input woes

Have the latest firmware update on my 1DC. There are 3 issues I am hoping someone can help with
#1 I assume you must set Sound recording to 'Line input' and NOT manual, but if I set the Rec level, whenever the camera is powered off, either automatically or manually, this Rec level is ALWAYS reset to zero. Also, the moment recording is startted, even though audio input levels are set correctly, no audio is recorded. This seems like a firmware bug to me. This does NOT happen when set to manual. Anyone know of a workaround?
When using Manual and plugging in an external audio source I assume this signal will override the audio from the camera's internal mic.
If this is correct and there are no issues when using 'Manual', then what is the difference between 'Manual' and "Line input'??
#2 When setting Sound input to Manual, the VU meters are visible, but NOT when set to Line input. Why?
#3 Can anyone recommend a specific connector to go from line out on a Zoom H6 to Mic in on the 1DC?
Solved!
Go to Solution.

No. Apparently a buggy firmware release. My understanding is that there is another release planned soon. Hopefully with several new (and working) features in addition to the line input.
Using Manual with a -25dB cable for now.

Line input failed

I can't get any line input signal to show up now, either in OSX or in XP Pro (bootcamp). My input source is not a mic, so I know reduced input voltage is not the issue. I also know that I have the Audio Midi Setup settings properly configured.
I've tried this in Audacity & QT Pro 7.5.5 on OSX & in sound recorder on XP. It appears that there is no input signal to be had through the line-in. In the past I could get a signal through line-in. I know the cable input cable is good, I know the signal is coming through the input cable, but there is no line-in signal showing in the applications.
I saw some old, archived forum discussions about this problem, which suggested that the issue was related to OSX 10.4 updates 10.4.10 and later, but there were no answers or solutions there. The fact that the problem appears in both OSX and XP leads me to think it may be hardware and not software.
Any ideas?

Hello: Thank for your answer, I took some of your code, and did this:
# Check the number of arguments that could be passed.
if [[ ${#@} != 2 ]]; then
echo "Wrong # of parameters...Use: check<inputfile> <outputfile>\n"
exit
fi
#Inputfile: is in position 1 on the ARGS
inputfile=$1
#Outputfile: is in position 2 on the ARGS
outputfile=$2
MIN_LENGTH=100
MATCH_PATTERN="5698"
#Read all the lines of the file.
# Notice: "read -r" Do not treat a backslash character in any special way.
# Consider each backslash to be part of the input line.
while read -r line
do
len=${#line} #Store the length
pattern=${line:0:4} #Store the first x chars for contrast with [MATCH_PATTERN]
if [[ "$len" -lt "$MIN_LENGTH" && "$pattern" = $MATCH_PATTERN ]]; then
(( ++count ))
echo "$line" >> "$outputfile"
fi
done < "$inputfile"
printf 'Number of registers: %s\n' "$count"
But I have some questions:
I) In your code, why use:
done < inputfile
. I don't get it. With the "while" is not enough to read all the file.
II) Is it OK to use inputfile=$1 and outputfile=$2 that way?
III) I did not find why (( ++count )) works in shell! Using
let count = count + 1
works, but that way you did it is more elegant.
IV) Puting "exit" at the end is redundant?
Thanks for the guide, is more compact that the one I was/am reading

Time code and line input

Greetings all,
I am trying to import 16X9 beta footage into my FCP. Since I don't have a Kona card or other direct imput device, I am having to go through my JVC BR-HD50 tape deck as a line input. Then set the FCP to import from a noncontrolable device. It works, with only one problem. I obviously can't get the original timecode that way. Is there a way to change the time code once it's in FCP or, is there a way to do it as it is being brought in?
Any hideas?

Sure. Determine what it should be in each clip you capture, then select a clip, and from the modify menu, select timecode... it will change it in the media file to be what's on the tape.

Audio Line-Input defect!

1. The Line-Input of my Macbook Pro 2.8 (late 2008) records phase-inverted! This happens with both Windows and OS X, so it seems to be happening in hardware.
2. The Realtek Windows driver shipping with Boot Camp is badly bugged. On the Input it clips everything above -12 dB hard, but only on the positive side of the waveform (negative is unharmed)! Fortunately this is fixed with the current R2.14 drivers.
This leaves the question of whether Apple has ever tested the line-input of it's shiney and expensive new Macbook Pros!?

****, the phase-inversion turned out to be the cable. You may call me stupid now!

Dear Jutapa.
While i am occupied with electronics for more from thirty years, my experience in the web pages has age of fifteen days. Thus your comments about the appearance of my site are precious and be compelled to you. Thanks, but i do not understand what means ?IMO?. Also, what means that my site is very hard? Please inform me to correct it. Now the answers in your questions:
) Perhaps you decei'ved from the size of transformer because it is only 50VA (or 50W / 30V = ,66A) and his cost in Greece does not exceed the 8?. Keep in mind always that, the toroidal transformers cost at 70 percent least from the E-shaped transformers. But in any case the total cost of the unit does not exceed the 45?. Surely this cost approaches the cost of the available mini mixing desks in the market. But the sound quality of the unit is comparable only with the high quality professional mixing desks, because the structure of circuit is precisely same with a channel such desk, a thing that appears and only from the supply of +/-8Volts. The phantom power of 8Volts maximum is enough for all modern condenser microphones. There are in the market such type units from famous brands as dbx, bss, apex, rane, symetrix, dda etc. and their price exceeds the 300? as these units are addressed for use in studios.
2) The oscilloscope graphs quoted in the article, believe me it is the better method of estimate the unit ? especially the square wave response ? because they express her transient character as this is most important for a designer of electronic circuits while the usual graphs of THD+Noise are offered more for consumers. If study my article, you see somewhere my explanation about this. Anyway, the T. I.M. factor of a closed loop circuit (Transient Intermodulation Distortion) expresses the possibility of it to manage the harder signals ? this is the response ?speed? to fast transients ? without oscillations. In the software of my oscilloscope included and a FFT analyzer to give the THD but i do not use it because by default today yet the chipper units in the market has very low THD due to the evolved modern electronic parts. The same is also in effect for the noise produced by the circuit himself. As it is known, the fundamental Johnson noise or thermal noise from metal film resistors is too little and the NE5532 ? NE5534 produce noise of certain nanovolts.
3) About the EIN (Ein) - or the sensitivity of input so that us understand also the other ? reported in the schematic diagram in dBV. Why not in dBm? Because from habit i do not want to take into account the input impedance ? as get used almost all the designers of electronic circuits ? and in this way the logarithmic expression of the minimum gain of input it is given by the use of dBV (reference ratio to Vrms). Let to calculate the input sensitivity in dBm as you prefer: The input impedance of the balanced input is: Zin = R2+R3 = 20 K? approximately. The total gain of input presented at the output of the subtructer U2A and is: V = V3-V2. The minimum gain of the first stage composed by the two non inverting UA and UB with VR5 turned full CCW is: Av = +[2X(R4+R3)/VR5+R5] = +[2X000/47220] = +0,466 = ,466. In dBm the reference is 0,775Vrms thus Av = ,466X0,775 = ,36Vrms. And because the output of U2A is twice his inputs then: V = 2X,36 = 2,272 Vrms and the sensitivity in dBm is: Ein = 20 X log(2,272 / 0,775) = 9,34 dBm. And if we take the maximum gain of the first stage - by turning VR5 full CW - of 0 with the same equations in dBm, results: 46 dBm

Line Input Hardware Unrecognized after 10.6.2 Update

Both my Macs (Pro and iMac) don't recognize Line Input hardware (headset and stand alone mics) after the last update. Under Midi Setup, mute is unchecked and all other settings appear normal. I do lots of recording and this is a huge problem...HELP!

No, not using USB; standard 1/8 jacks.
The System Profiler shows that I have numerous input/output combos and such. But, the actual devices I'm connecting don't show up. Should they on the Profiler?

Considering a Macbook pro 13". want to use garage band - how do i run line in from my guitar. There is not a mic/line input that I can see in specs.

Simple. GarageBand question, GarageBand forum where all those users are jacked into their Macs and can tell you how. Also look to the right of your post to the column, "More Like This."---------------------------------------------->

Equium A100-306: Question about stereo line input recording

I want to record to my laptop and as, frustratingly, it hasn't got a stereo line input.
I have acquired a Behringer USB line adaptor (UCA202). This allows playback through my stereo system (with adjustable output level through the sound card) but input level is too high and can't be adjusted by any means I have tried.
Is there a solution to this that can be followed by an enthusiast?

Thanks for the information. I shall explore the software option as the thread you mention looks very relevant even though it relates to a different model.
If that doesn't work or proves too complex to install/configure I thought the Echo Audio Indigo IO sound card might do the trick.
It's ironic that the Equium A100-306 was sold as a multi-media laptop but doesn't have a line input.

Where is the line input on my hdx16 laptop?

Is there a way to change the external mic jack to a line input?

You will need a USB device to which you can connect an input cable. If your cable uses a 3.5 mm mini-plug, then you can try using a device such as the Griffin iMic or any similar USB sound card that has both input and output jacks, connects to USB, and conforms to standard USB protocols not requiring any special drivers to work on a Mac.
Here'sone other such candidate. Google searching will likely find you many others.

Audigy 2 ZS: Keeping line input from playing on speak

I recently installed an Audigy 2 ZS in a Win2k machine. In the mixer, I've selected "Analog mix" for recording. So "What-U-Hear" should be off, right? And I have disabled "Monitor during recording." So, while recording, I don't hear what is coming in the line input. But if I turn recording off, suddenly what's coming into Line-In blasts out the speakers. Is there a way to permanently disable passing Line-Input to the speakers when I'm not recording or even running a recording program?
Bob

The mixer device list for the Audigy 2 ZS shows a separate Line-in for record and play. So it appears that the ability to keep Line-In from playing on speakers is there. However, unfortunately the Creative Mixer implements this as a record option and an option to "Do not monitor while recording." With this option checked, Line-In isn't passed through to the speakers but only during recording. At other times you'll hear what is coming into the Line-in. By comparison, the Audigy 2 LS has an option to "Do not monitor," which blocks Line-in pass-through under all conditions (unless an api enables it). The Line-In pass-through was a particular problem for me for a C++ program I've written. So I solved the problem by selecting "Do not monitor while recording," muting the global volume, and un-muting the global volume with a call to the mixer functions when I turn on recording from within my program. This prevents pass-through even when my program isn't running, which was important for my particular application. Unfortunately, this isn't a viable option for someone using an off-the-shelf recorder-player. Other mixers might implement this differently.

I have updated the drivers just a few weeks ago.
Hints?

I just bought the audigy 2 ZS line input h

I was hoping that I could use the "line in" for my stereo input but I can't seem to be able to get it to work. I know it is something I just have to click on but I don't know what.

baloce,
Check the mixer to see if it's set up correctly. If you have your source connected to the line input, it should be fine. In the mixer check the normal slides to see if the line in volume is turned up. In the red slide, check you have the line in/analog mix selected for recording.
