why no audio

[natty]

I have this tutorial clip. but there is no audio to it yet in gspot it says this mp4a: MPEG-4 AAC LC i have tried 2 movie players but still no sound I am on windows 7 do I require a codec to hear sound then

[Selur]

VLC, SMPlayer or similar players which come with their own decoders should help playback such content if you lack decoders for it.

[Selur]

does it indicate that there is sound?
may be the problem is your audio configuration not the playback itself,...

this is what vlc player shows for info

[Selur]

if you enable an audio visualisation in vlc does it show any changes during playback, if it does vlc decodes the audio and something is wrong with your general audio configuration

[Hoser Rob]

It may well be your audio config. Can you play other videos with aac audio?

It'd be good to post mediainfo text output on the file here.

I've seen weird things with seemingly standard formats. Often these videos were encoded by people who had wacky codec packs on their system that aren't really very windows compatible.

Last week I tried to play a video in smplayer but got no sound ... as selur mentioned, that and vlc are the "play anything" programs, and I've found smplayer actually better in that respect. VLC played the audio but the video used srt subs and vlc has crappy sub settings.

So I opened the video with avidemux, which actually could decode the audio (it's another "throw just about anything at it" program. Set video to copy, audio to convert to something else, it worked.

Another thing I've done when aviidemux didn't recognize the audio format was open the video with audacity. That's actually an audio editor/processor but if you open a video file it'll just open the audio stream. Then export to another format, assuming audacity can decode the format, which has always worked so far. Then. open the video in avidemux, load the audacity output file, set both video & audio to copy, and save.

i tried all of the above didnt work, when i try to load into Audacity it says formatt must be wav or Aiff




can no one help anymore on this as I have uploaded mediainfo snapshot and i don't appear to be receiving anymore help

why do people start to help you here then dont come back to help anymore

That's quite strange, especially since you're running windows 7 and aiff is an Apple format ... what are your settings?

You're whining less than an hour after someone posted on your thread?

I'm done here .,..

For Audacity, download and install the ffmpeg plugin package.
You should then be able to access many more audio formats:

Um, did anyone notice the 3 thousand bits per second bitrate????

(approximately 1 bit to every 28 samples)

Hi this seems too complicated to do I have downloaded what it says but cant find the dll files req by audio city

I apologies for my reactions, and yes you are right I have a bad fault when waiting for a reply. I just thought as i was getting replies then it stopped I didn't know what else to do. so please accept my apologies for that. I quite understand if you dont want to help anymore

settings for what ??

Download MKVTOOLNIX, load the file in question into MKVMERGE (MMG.EXE) and create a file with only the audio in it and post the MEDIAINFO for it. If it really only has a bitrate of 3000bps then it must be nothing more than silence.

I have downloaded what you said and loaded clip into it, then i clicked on start muxing is this what you wanted to see as clip still has no audio

[ndjamena]

We need you to separate the video and the audio, just to make sure 3000bps is an accurate bitrate for the audio and not just a bad calculation based on the bitrate of the video.

Remux the file again and uncheck the video this time.

[ndjamena]

[AN FYI ANYONE READING THIS]

I just tried to make a 3000bps AAC with NeroAAC. Not only does it sound like crap but the actual bitrate Nero used was 9 496bps and it seems to have gone bonkers just trying to make that.

Bit rate : 9 496 bps
Format profile : HE-AACv2 / HE-AAC / LC
Channel(s) : 2 channels / 1 channel / 1 channel
Channel positions : Front: L R / Front: C / Front: C
Sampling rate : 48.0 KHz / 48.0 KHz / 24.0 KHz

I'm assuming it's switching profiles midstream in an attempt to deal with the excessively low bitrate, 3096 simply isn't a valid AAC bitrate, especially at low complexity.

looking at the file name goolge send me to: http://www.youtube.com/watch?v=FiJ_YcNChKw
which is a video without sound. (silent sound)

[ndjamena]

Mystery Solved!!!

so why does it show a audio file then with video don't make sense

[Selur]

silent audio = an audio stream with a flat audio stream in it. (Audacity should confirm this)
afaik Google adds silent audio streams to files without audio, probably something to do with their internal processing routines
Since you didn't tell us about the source of your file I'm not sure that the file I linked to is the same file you are looking at, but if it is you have your explanation.

yes that is the file you searched on google How to Repair and Restore Old Photos in Photoshop Tutorial - TutorialCraft such a shame really as sound would have been much better with it. I honestly dont know why people make a tutorial like that with no audio but anyway it seems there is no sound to this file pity really

[ndjamena]

It has graphical text for you to read and that's all it actually needs. If you really want audio find some nice, melodious background music, edit it to size, encode it to AAC and add it to the file.
