Duration: 01:00UCS Category: TEST (?)The UCS, for "Universal Category System", is a public domain initiative by Tim Nielsen, Justin Drury and Kai Paquin, among others. This is a list of fixed and consistent categories for classifying sound effects. It provides consistency in a filename structure to make naming and categorizing easier for anyone who maintains their own personal or professional library. This sound library meets the UCS 8.1 categorization. Click to display the full UCS list.Type: SoundscapeChannels: Stereophonic (?)- Monophonic : Is single-channel. Typically there is only one microphone, one loudspeaker.- Stereophonic : Is a method of sound reproduction that creates an illusion of directionality and audible perspective.- Ambisonic : aims to create a multi-channel sound space. Used, for example, in virtual reality.Conditions: Studio (?)A "studio" sound has been recorded in a reverb-free place.An "outdoor" sound contains disruptive elements. The sound is not totally pure. There is sometimes a little wind, some rumors, etc.A "indoor" sound usually contains a strong reverb. It can not, for example, be used to sound an image taken outdoors.Realism: Idealized (?)Un son "Real" à été enregistré en condition réel. Par exemple : Un brossage de dent avec dentifrice.Un son "Idealized" à été enregistré en condition réel mais en ne gardant cherchant à coller au plus près de l'idée qu'on se fait de ce son. Par exemple : Un brossage de dent sans dentifrice.Un "Foley" à été enregistré en studio, avec des astuces de bruiteurs. Par exemple : Un brossage de dent imité avec une brosse à ongle.Sampling Rate: 48,000 Hz (?)Search : Defines the number of samples per seconds taken from a continuous signal to make a discrete signal. The unit for sampling rate is hertz.- 44,100 Hz : CD Audio quality.- 48,000 Hz : The standard used by professional digital video equipment such as tape recorders, video servers, vision mixers and so on.- 96,000 Hz : DVD-Audio, some LPCM DVD tracks, BD-ROM (Blu-ray Disc) audio tracks, HD DVD (High-Definition DVD) audio tracks.Bit depth: 16 Bits (?)More : In digital audio, bit depth describes the number of bits of information recorded for each sample.- 16 bits : CD quality audio. A standard used by media professionals.- 24 bits : DVD-Audio, which can support up to 24-bit audio.Author: Joseph SARDIN
Silent Wav File For 1 Second Download

Here is the solution I found. It turns out you can upload a custom sound file to your smartphone and use it. For that I generated a small WAV file - 0.1 seconds of total silence. 1) You can download it from here:
2) Now you need to put it into a specific directory in the memory of your smartphone, called "Notifications". To do this, you need to use an app that allows to freely manipulate files and directories, as opposed to just looking for specific content as image or music players do. If you downloaded the file directly to your smartphone, use free Total Commander to move this file to the "Notifications" directory. If you have it on your PC, MyPhoneExplorer will be a good app to connect to your phone using a USB cable or WiFi network and transfer the file.
3) Finally, you need to select the file in Messenger. To do this, go to its settings > Notifications & Sounds > Notification Sound. The new file "Silence_100ms" should appear mixed with the list of default sound effects. After choosing it, your message notifications in Messenger will be silent.
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):
This is a ffmpeg wrapper that will take in multiple audio files and combines them into a single file. Silent gaps will be put between the parts so that every new part starts from full second and there is at least 1 second pause between every part. The final file will be exported in mp3, ogg, ac3, m4a and caf(IMA-ADPCM) to support as many devices as possible. This tool will also generate a JSON file that is compatible with Howler.js or zynga/jukebox framework.
This page gives you access to high definition audio test files, with sample rates as high as 192 kHz. Unlike our other sections, these sounds won't play online: higher sample rates are not your browser's best friends, and cannot be encoded in the mp3 format either. Instead, these high definition files will download straight to your disk as uncompressed .wav files.
These files do play frequencies that are above the human hearing range. Don't try to hear a frequency that you will never hear anyway. NEVER TURN THE LEVEL UP beyond a reasonable level. USED IMPROPERLY, THESE FILES WILL DAMAGE YOUR HEARING OR YOUR EQUIPMENT. If you are unsure how to use these files, please do not download them.
The test starts by playing frequencies that are in your hearing range, and then they will steadily increase. As the sweep enters ultrasonic range, the sound will fade away. Listen carefully; the rest of the file should remain perfectly silent.
Chirp tones are similar to sine sweeps, but span the whole frequency range in a much shorter time: here 0.5 seconds. Each chirp tone plays at -3 dBFS. Use these files to measure frequency responses, or capture room reverberations through the impulse response method.
Pink noise is characterized by a power spectral density that is inversely proportional to the frequency: each octave carries an equal amount of noise power. All files are 30-second long, and play at -3 dBFS.
As a result, WAV files can take up quite a bit of space, taking up about 10 MB per minute. So if you've got some audio you need to crop out of your file, it's best to get rid, as it could save you some precious storage space. Read below to find out how to do so online, for free, without needing to download any complex audio editing software.
This next step requires you to get your virtual scissors out. The image in the centre of the screen visually represents your audio file. You can crop the length of this easily by simply moving the two blue markers, or by inserting the exact start and end times in seconds in the boxes on the right-hand side.
The above-periods value is used to indicate if audio should be trimmed at the beginning of the audio. A value of zero indicates no silence should be trimmed from the beginning. When specifying an non-zero above-periods, it trims audio up until it finds non-silence. Normally, when trimming silence from beginning of audio the above-periods will be 1 but it can be increased to higher values to trim all audio up to a specific count of non-silence periods. For example, if you had an audio file with two songs that each contained 2 seconds of silence before the song, you could specify an above-period of 2 to strip out both silence periods and the first song.
Use MP3 files for web pages, web videos, in fact for anything on the Internet. An MP3 file is a compressed music file. It loads rapidly and still plays with a very good sound quality. There are several levels of possible compression but for Internet usage we recommend 128kbps which is what you download automatically from our server when you order music from us. If your project requires a different level of compression you can easily do it yourself with iTunes using the .WAV file supplied with your order.
MP3 files are the sound part of an MPEG file. They are incredibly popular with users because the audio files are compressed to about one tenth of the original size. As a result, they take up very little disk space and are quick to download. At the same time, they are able to deliver audio that is almost CD quality. This is why MP3 files are the natural choice when people want music for websites or multimedia presentations.
If you still have problems when you listen to the recordings across the Internet, right click and choose Save As in order to download the file to your hard drive and listen to it locally.
A problem has been experienced with certain combinations and configurations of IE and the audio player that prevents the download of these sample files with a normal mouse left click. The sound player sends an error message which indicates that the file cannot be found. If you encounter this problem, use these workarounds:
The largest file in this document is 900KB in size and it takes over four minutes to download on a 28kbps link. Most files are much smaller and take much less time. If you have this problem, review these workarounds:
Some smaller snippets of the sample files have been produced and are located in another column of the table. The size of these snippets ranges from approximately 60-150KB. The largest file takes about 40 seconds to download and smaller ones less than 10 seconds.
Ensure the file has been downloaded. Look for any error messages from your sound player, in particular that indicate that the file cannot be found. In which case, see the The Sounds Do Not Play Directly from the Document section.
