Thank you. I guess what I am trying to do is use chains to insert either 1.0, 0.5, or 2.0 seconds of silence per audio track as I select them. Unfortunately it appears that the silence is added to all of them.
Basically I need to join audio clips to form greetings for our IVR. for example, I need to join file 100, 101 and 102, after 100, I want a 1.0 second silence, after 101, I want a 0.5 second silence and after 102, I want 0 silence. I then take the new audio file and export it to a wav file.
I have an AC3 5.1 audio file to which I would like to insert x seconds of silent audio at the beginning. This has nothing to do with video muxing, so itsoffset is useless since it seems to only work with an audio stream accompanying a video one. I would like to achieve this with ffmpeg. Any ideas?
Use the anullsrc audio source filter in to create the silent audio. You'll need to match the format, channel layout, and sample rate of the main audio file. Example to make a 5.1 channel, 48000 Hz sample rate, 1 second silent AC3 audio file (as this was what the format in the question):
Use the concat filter if you want to do everything in one command, or if you want to output to a different format than the input (since this method re-encodes anyway). This methods works for adding silence to the beginning or end or both.
Use the adelay audio filter if you want to do everything in one command, or if you want to output to a different format than the input (since this method re-encodes anyway). This only works to add silence to the beginning of a file.
Use the apad audio filter if you want to do everything in one command, or if you want to output to a different format than the input (since this method re-encodes anyway). This only works to add silence to the end of a file.
It is from here that we begin the third issue of the We Who Feel Differently Journal with a focus on HIV/AIDS, a look at the recent past, and the current moment to both unearth the conversations had and the work produced within the second silence, and to share ideas and conversations that are taking place now.
Introduction: The term 'second victim' refers to the healthcare professional who experiences emotional distress following an adverse event. This distress has been shown to be similar to that of the patient-the 'first victim'. The aim of this study was to investigate how healthcare professionals are affected by their involvement in adverse events with emphasis on the organisational support they need and how well the organisation meets those needs.
Discussion: This article addresses the gap between the second victim's need for organisational support and the organisational support provided. It also highlights the need for more transparency in the investigation of adverse events. Future research should address how advanced support structures can meet these needs and provide learning opportunities for the organisation. These issues are central for all hospital managers and policy makers who wish to prevent and manage adverse events and to promote a positive safety culture.
Crazy long reverb/FX times: I thought that there might be some insanely long tail on a reverb/delay plugin causing long tails that though inaudible were technically still there. Even when I export with these plugins removed, this extra silence is still there
I thought the better quality and higher version of the bluetooth could solve my old problem with my old headset, I still lose the first half second of audio when starting the tracks or jumping from one to the other. I often have to listen to really brief sound effects, some of them of about one sec and the majority of the time I can't hear the sound.
I have a couple tracks on an EP that I want to flow into each other, so I set the end of the bounce precisely how I want it. But when I bounce it, the file has maybe a second of silence after my desired ending spot. Any help?
What I want to do is to have a song's instrumental and vocal versions both scattered into few identical parts so that I can choose which version I want to play atm. Problem is the transition between the cut tracks is not seamless because Pr leaves few seconds before and after making it having pause in between them.
In my project/sequence whatever I have 2 songs aligned and both cut into 3 parts. Start middle and end, both in muted channels. Let's say I bring the middle part up into non muted channel, select it in and out based on the selection and export it as .mp3. But the exported middle part has one millisecond before and one millisecond after in addition to the selected part. Problem is that the milliseconds prevent flawless loop if I want to play it repeatedly.
I'm a little confused with an issue that I keep running into. I'm trying to create some sound loops for continuously playing, seamless background music.. everything's fine as long as I stay in AAC/ WAV/ etc, but as soon as I encode the files in AAC I run into a 1/10 of a second at end of the sound file.
Please take a moment to consider if this thread is worth bumping.Questionprincealexis26Posted August 3, 2019princealexis26Resident
Whenever I want to play something with sound, no matter if it's a YouTube video on Chrome, Edge or a desktop app, about the first two seconds of sound will be silent, thus missed, so I have to rewind or replay whatever I was playing to hear it again. Then the sound is fine, until there's no sound for about 30 seconds. Then it will happen again, when I want to play something, it will start to play muted for the first second or two, then continue normally. This is very annoying because I have to constantly rewind every new video I watch, and I work with music and my notation software will do the same thing, no sound for the first second or two after the computer has been silent for half a minute. This happens either with the computer plugged to power supply or with battery mode. This doesn't seems to happen 100% of the times, but like 80% to say the least.
It feels like the laptop goes on 'audio power saving mode' after a time of silence, so when there is sound again they 'wake up' but they need almost 2 seconds to do it. This is a huge problem for me as I work with audio, I can't be missing the first seconds of audio every time, I bought this laptop to have a powerful and portable audio workstation but now it almost feel like I just threw more than $1000 into the sewer.
I'd really appreciate a fix for this. I don't care about HP Omen audio control cool enhancements or if the speakers are bang&olufsen, I just need a plain audio system which allows the computer to play sound whenever it has to be played, without delays or interruptions, either with laptop built-in speakers or with headphones or second pair of speakers.
It looks like it's what I said some posts earlier, some kind of power saving feature disables the audio after a 30 second silence, then it has to "wake up" whenever you play something, even if the laptop is plugged to power. I don't think this feature helps with battery life, so I don't get the point of it, but I'd like to know a reason why this feature exists, if it doesn't exit with Windows High Definition Audio drivers...
Anyway, it seems that the registry edit in said post overrides the power saving mode for the realtek driver, so this problem is not happening anymore. All speakers work fine, no audio delay or silences, and I can use stereo mix. I'll come back if I have any problem, but for now it looks everything's fine.
I just installed drivers from Realtek website while I had a second pair of speakers plugged into the headphone jacks. The drivers installed properly for these speakers and the problem is gone, BUT only when I use an external device on the headphone jack, now the built-in speakers of the laptop won't work, even when there's nothing plugged in.
I want to be able to use both my built-in speakers and my external devices without audio issues or delays, is that so much to ask?
Right now I just have two options:
Be able to use all the speakers but get audio delay at start whenever I play something. (By installing HP Recommended drivers)
Be able to use only external audio devices but get sound right. (By installing Realtek site drivers while second speakers are plugged)
If I install audio driver by the HP Support Assistant software, it installs the Realtek drivers with the "OMEN audio settings" feature. This way, built-in speakers work fine, but when I use headphones or any other speakers plugged to the headphone jack, there's a 2 second delay before sound start playing. To avoid confusion, I'm not saying that audio is out of sync, I'm saying that audio output is silent for the first 2 seconds, then plays correctly. This happens almost everytime after the computer has been silent for 30 seconds or more. So almost every time I'm going to watch a video or play something on my computer, I won't hear the first two seconds of audio so I have to rewind.
