Newbie to Sound

I have 2 questions about sound in Flash:
1. Does frame rate affect sound quality at all? Or they're
two completely separate things?
2. If size is not an issue, among aiff, wav, and mp3, which
is the best sound format for Flash in terms of sound quality,
handling, and performance?

First of all, when you import sound into flash, change the
default settings because they use high compression on sounds and
you get poor quality audio.
You can do it in Publish Settings / Flash tab.
There is a section called "Images and Sounds".

Sound Waveform Average

I'm a newbie to sound concepts and I've run into a problem. Our test set-up has six microphones set up in a reverb room. The first phase is to read from each microphone for a specified amount of time and average those readings. To accomplish this I built an array from each microphone in a while loop over the specified time interval. When the loop is done executing the average of each array is calculated. My question is how to take the now six averaged arrays and come up with one single waveform that I can use with the Octave Analysis function in the Sound and Vibration tool kit? I'm using LV 8.2.1.
Thanks.

Hi MeCoOp,
If you're new to SVT you might want to take a look at the LabVIEW Example
Finder (which you can find from Help»Find Examples) under Toolkits
and Modules»Sound and Vibration»Getting Started. Is there a specific part
of the application that you're having trouble with? Do you already have a code
that gives you six arrays and you are simply trying to get an averaged waveform
from them?

EDITING SOUND/MUSIC in SOUNDBOOTH or PREMIERE PRO CS3

I have a question that has been posed to me about sound/song/music editing. How can one either in SOUNDBOOTH or in PREMIERE PRO CS3 - edit the playback - so show beat by beat - is that possible?
I'm not musically inclined. If I want to cut/edit a sound and match it with a similar of another - how can I go about that?
please email me as i'll forget to check here for replies - [email protected]
thanks for any suggestions. I'm a newbie at sound.

You can use either one for what you're talking about.
You will find links to many free tutorials in the PremiereProPedia that will quickly show you how things are done in Premiere Pro.

Setting classpath in WebLogic 7.0

I'm a WebLogic newbie.
I've developed some simple EJB and everything works fine.
I want to add an external package (jar file) to the classpath but
can't figure out how to do it.
Detailed help will be most welcome (which file to edit or directory to
throw your jar files in).

If your a newbie this sounds daunting I am sure.
But if your going to do do this easily and right, pick up a book on Ant, it will
easily build jar's with manifest classpaths.
This is much easier in 8.1 coming soon..... stay tuned.

Converting audio samples using libav*

Hello guys,
I've been looking for a solution for several days by now and have not gotten any smarter, I hope that someone of you is able to help me
What I'm currently working on is an application able to generate audio fingerprints (specifically acoustID fingerprints). To do so, I started with the sample
code that demonstrates the basic fingerprinting capability. You can find it here.
It is part of a library called chromaprint.
As you will see, a lot of this code uses deprecated functions. As a newbie to sound conversion, the sense of a lot of the calculations in the file is oblivious to me
Still, I want to renew the code to use functions that are up-to-date. Ideally I'd understand the code more thorough then, or so I thought.
I started modifiying the decode_audio_file function from fpcalc.c and got until here, where I am now stuck:
int decode_audio_file(ChromaprintContext *chromaprint_ctx, int16_t *buffer1, int16_t *buffer2, const char *file_name, int max_length, int *duration)
AVFormatContext *format_ctx = NULL;
AVCodecContext *codec_ctx = NULL;
AVAudioConvert *convert_ctx = NULL;
AVStream *stream = NULL;
AVCodec *codec = NULL;
AVPacket avpacket;
AVFrame *decoded_frame = NULL;
FILE *f;
int frameFinished = 0;

int buffersize = AVCODEC_MAX_AUDIO_FRAME_SIZE + FF_INPUT_BUFFER_PADDING_SIZE;
uint8_t inbuf[buffersize];
/* initialize data packet that is read from the stream */
av_init_packet(&avpacket);
avpacket.data = inbuf;
avpacket.size = buffersize;
/* make space for frame that contains decoded data */
decoded_frame = avcodec_alloc_frame();
/* tell format_ctx about the input */
if (avformat_open_input(&format_ctx, file_name, NULL, NULL) < 0) {
fprintf(stderr,"ERROR: couldn't open the file");
goto done;
if (avformat_find_stream_info(format_ctx, 0) < 0) {
fprintf(stderr,"ERROR: couldn't find stream information in the file");
goto done;
for (int i = 0; i < format_ctx->nb_streams; ++i) {

codec_ctx->sample_fmt, 1);
if (convert_ctx) {
const void *ibuf[6] = { decoded_frame->data };
void *obuf[6] = { buffer2 };
int istride[6] = { av_get_bytes_per_sample(codec_ctx->sample_fmt) };
int ostride[6] = { 2 };
len = data_size / istride[0];
if (av_audio_convert(convert_ctx, obuf, ostride, ibuf, istride, 4) < 0) {
fprintf(stderr,"WARNING: unable to convert %d samples\n", len);

fprintf(stderr,"ERROR: fingerprint calculation failed\n");
goto done;
ok = 1;
done:
avformat_close_input(&format_ctx);
avcodec_free_frame(&decoded_frame);
return ok;
You can find the documentation for the used chromaprint functions here.
As I said, I am not really sure whether I have understood all of what is going on in the unmodified version of the function, so please bear with me
Any answers or suggestions for reading material will be gladly appreciated!
PS: goto marks will be removed once the code works

First slice the track using the Strip Silence function (in L9 you could also use Flex mode to splice the track), then convert all the resulting regions into new Audio files using the copy/convert function. Then drag all those files into the EXS (hit the edit button first) using the contiguous mapping feature, set the lowest note to C0 or wherever you want the mapping to start.

Voice transformation/conversion/morphing

Good day all,
My final project is about voice conversion where there is a source voice and a target voice. The source voice contains the words that should be spoken using the target voice. I am a newbie in sound manipulation. I have read little about DSP spectrum analysis, windowing, dft, lpc... My current progress so far is opening a wav file as audioInputStream after that I am lost. I need help to clarify the process/stages that I should do to perform a voice conversion. Also, is there a free package that contains functions for voice conversion?
thanks a lot all:)

Newbie question: Why is "learn sound model" greyed out when trying to remove background sounds in a file using the Spectral Frequency display?

I am trying to remove background sounds in a file using the Spectral Frequency display. The first edit on a new file, this process works fine:
1. use brush to cover sound
2. right click, learn sound model
3. effects/noise-reduction-restoration/Sound Remover
The next time I try to remove another sound in the file, "learn sound model" is greyed out. I have to close the file and reopen to be able to make another edit. What on earth is going on? Can it only learn one sound model or something?
I'm a newbie, so thanks in advance for your advice!

My daughter has had her Razr for about 9 months now. About two weeks ago she picked up her phone in the morning on her way to school when she noticed two cracks, both starting at the camera lens. One goes completely to the bottom and the other goes sharply to the side. She has never dropped it and me and my husband went over it with a fine tooth comb. We looked under a magnifying glass and could no find any reason for the glass to crack. Not one ding, scratch or bang. Our daughter really takes good care of her stuff, but we still wanted to make sure before we sent it in for repairs. Well we did and we got a reply from Motorola with a picture of the cracks saying this was customer abuse and that it is not covered under warranty. Even though they did not find any physical damage to back it up. Well I e-mailed them back and told them I did a little research and found pages of people having the same problems. Well I did not hear from them until I received a notice from Fed Ex that they were sending the phone back. NOT FIXED!!! I went to look up why and guess what there is no case open any more for the phone. It has been wiped clean. I put in the RMA # it comes back not found, I put in the ID #, the SN# and all comes back not found. Yet a day earlier all the info was there. I know there is a lot more people like me and all of you, but they just don't want to be bothered so they pay to have it fix, just to have it do it again. Unless they have found the problem and only fixing it on a customer pay only set up. I am furious and will not be recommending this phone to anyone. And to think I was considering this phone for my next up grade! NOT!!!!

Sounds like a newbie question... help!

hello people,
i have a mega 180 and i am not sure on how to go about reformatting this pc. sorry if this sounds incredibly newbie but the options in the bios is different from what i usually encounter on my old hp computer. when i change the options for primary master and secondary master, i can't seem to choose my cd rom as the primary master. all i get is auto manual or none. i would be extremely appreciative if anyone could help me out. thanks!

That's a different option in the BIOS. Can't remember exactly what menu it's under, but I think the second one. Then there's an option for "First Boot Device", change that to say CDROM. And change "Second Boot Device" to be your hard drive, most likely HDD-0 (that will be your Primary Master - the one you will boot the OS from).

Newbie: subtitling without sound in LT?

I'm a FCE and LT newbie, although I have experience working with video editors in Windows.
I need to create subtitles for a movie. I exported the movie from FCE and placed it "behind" in LT. But because LT does not support sound (correct?), I don't know exactly where/when to place my subtitles. And FCE doesn't create text, correct?
So I'm wondering how does one place subtitles accurately with spoken words. My subtitle search on this forum brought very little.
Do I have to create a different LT file for each line of dialogue and then import each line into FCE? Right now, that's the best I can come up with. Is that standard procedure? Other suggestions?
Thanks for your indulgence. I would appreciate any input.

LiveType does not support audio.
One workaround is to place markers in your Final Cut timeline. Press M twice to place a marker and call up the dialog where you can give it a descriptive name. You can then export a reference movie with markers which will show up in LiveType.
FCP includes a simple text generator and Boris titling tools. FCE should at least have the simple one. Click the little film icon with an A on it, at bottom tight in the Viewer. There should be a list, one of which is labelled Text.
Do I have to create a different LT file for each line of dialogue and then import each line into FCE?
No, just choose Track > New Track from the menu bar and drag it to where you want it on the Timeline.

Newbie despaired: compressor 1.02 NO SOUND with H264

I'm a newbie, so please forgive my question, it could be a silly one.
I tried compressing a vob directly in compressor 1.02 to h264. I created a quicktime profile for it as there was none in compressor. I tried everything, but no matter what I get no sound in the compressed mov!
This is driving me nuts - I spent the whole of last night on this.
Can someone tell me what is wrong (sound works on my dual G5-tiger, no problem)
Gratefully and exhausted
Totoro

yes you got my problem right -oops demuxing... I haven't tried that one yet :-c I'm a graphic artists and i've been told by a client: there, we've got FCP on that G5, do you stuff... sigh, thanks dog there is a forum such as this one!!!
all advise most welcome (and no, the project is too small and short of money to pay a specialist to do it :-cc)

Playing sound using ActionScript 3.0 (newbie)

I have a Flash animation I've created, and at the last minute we have decided to add one audio track to the background. The problem is, I have a looping animation in the timeline, so simply inserting the audio into a layer in the timeline will not work (because it will loop as well).
Can anyone help me with how to insert just one sound file "on top" of all the animations playing using ActionScript 3.0? I've never worked with the Sound class, and have never put audio into a Flash file besides simply importing it into a frame.
THANKS!
Jen

Worked perfectly. Thank you thank you!

Getting sound every time I close lid.....never happened before..newbie help

I have had my MBP for about 3 months & love it.
Over the last 48 hours or so every time I close the lid to put itto sleep I hear a "sosumi" sound.
It still goes to sleep OK, but am I concerned as to why i am now hearing this sound.
Any help would be appreciated.
Thanks,
John

You wouldn't happen to have a instant messaging app running when you close the lid, would you? Every time I close my lid, I can hear the Yahoo Instant Messenger app make the sound indicating it lost it's network connection.
Or, perhaps, that alert sound indicates your network connection itself is terminated.

Bizarre Sound Distortion on Export - Not Newbie Compression issue

I'm trying out the Flash CS3 demo - OSX. (Using OSX 10.4.10.)
I've got a slightly complicated timeline with about 8 layers
and some things alpha fading in and out, and a bunch of sound
samples being used as timeline sound effects (forget the term, but
attached to frames not streaming). No scripting.
The sounds are mostly too long for the amount of time
allotted to them in the timeline, and cut previous sounds off. I'm
speculating this might be a possible issue. That is, I have say a 5
second sound, which has only 3 seconds of time to play, before
another sound interrupts it in the same timeline layer.
There are two separate layers of sound playing at the same
time.
All the original sounds are imported into the movie as
44.1/16bit AIFFs. They are mono files (might be another possible
issue).
I'm trying to export with quality of 128k MP3. I've been
trying different variations:
- setting the compression for the audio files in the
Library/setting movie export settings to use Library settings
- setting audio files in the Library to use "default
compression", and specifying the correct 128k MP3 setting in the
export settings
- or both of these (set individually in library, then
overridden in export settings).
I've tried with and without the "use mono" setting (both in
Library files and export settings). (This is a question for me:
what should be the correct setting for that when the original file
already is mono?)
Sometimes everything's great. I test or export the movie and
the sound is fine.
Other times I test or export the movie -- with exactly the
same audio settings as the last time when it worked -- and now get
unbearably hideous hissing/cracking instead of the correct sound.
Most dangerously -- I think but haven't quite convinced
myself -- the same flash export file may sometimes play fine, and
sometimes play with the distortion. So I'm not sure if this is an
export issue, Flash player issue, or combination of export doing
something semi-weird that the player only sometimes chokes on. A
"bad" export is distorted both in the desktop Flash player that
comes with the Flash demo, and in a browser with Flash plugin 9 r45
(OSX).
GUH!
And this is the $800 product which is little more than a
basic text editor for scripting and an animation timeline that
hasn't gotten updated functionality since 1999.

This is a peer-to-peer public forum - if you demand
individual and undivided attention to your issue
then you can use the official adobe tech support.
As for your issue...let's go step by step:
[*The sounds are mostly too long for the amount of time
allotted to them in the
timeline, and cut previous sounds off. I'm speculating this
might be a possible
issue. That is, I have say a 5 second sound, which has only 3
seconds of time
to play, before another sound interrupts it in the same
timeline layer.*]
Is this intended? You are having an issue with 5 second
sounds being cut off after 3 seconds...why
not place them on different layers to avoid this? I don't
understand the workflow here.
[*There are two separate layers of sound playing at the same
time.*]
Ok - that makes more sense, so you have 2 layers both
containing sounds that cut each other off?
[*All the original sounds are imported into the movie as
44.1/16bit AIFFs. They
are mono files (might be another possible issue).*]
Mono shouldn't matter - but the quality of the original will
matter - specifically the levels, if
the overall level is originally too high (or "hot"), then
clipping will occur once compressed from
Flash (in some cases).
[Sometimes everything's great. I test or export the movie
and the sound is fine.]
Can you provide the FLA?
[Other times I test or export the movie -- with exactly the
same audio settings
as the last time when it worked -- and now get unbearably
hideous
hissing/cracking instead of the correct sound.]
Never heard of this before - need to see the FLA.
[And this is the $800 product which is little more than a
basic text editor for
scripting and an animation timeline that hasn't gotten
updated functionality
since 1999.]
You may take exception to this but it sounds very much like
user error or something beyond Flash
(like an issue with the source audio files). Your opinion is
subjective but AS3, Flash, Flex is
hardly "little more than a text editor". True the timeline
hasn't changed much over the years but
funny that it is still the king when it comes to animation
across so many mediums - why fix what
ain't broken and works so very well for so many worldwide?

Newbie Question, Beep Beep Beep Sound

I've put my video clip in the timeline and I also put an mp3 file in the audio part of the timeline. When I drag inside the timeline I can hear my mp3 file but then when I go to play it back in the window all I get is a beep beep beep sound. Please help, I'm really frustrated!

FCP doesn't really support MP3 files. so it plays the beeps... open the MP3 files in QT pro, then export them as 48 kHz aiffs... edit with these new files, the beeps will go away.

Newbie - sounds not all loaded?

Hello all. Recent convert from a pc and sonar.
So far liking my mac and I just downloaded logic 9. Cool stuff. So I can use a good bit of the sounds but a large number of the organs I cannot use. The download hung on me so I had to restart the mac and then it resumed so I assumed it downloaded it all but now I'm skeptical.
Any thoughts on this as I do some classic rock / blues and I really like the organ behind it all. ;-)
