Silent CD Silent CD (& MP3s) What is this? A CD of silence. (Strictly not a CD of silence, of course, but audio files of silence which one can burn to a CD-R to make a CD of silence.) The tracks are of 2, 4, 8, 16 & 32 seconds and 1, 2, 4, 8, 16 & 32 minutes duration so they can be combined using the play list feature of a normal compact disk player to give any duration (in even numbers of seconds) from 2 s to an hour (well, up to 1 h 4 min 2 s, to be pedantic). Uses.

Novelty item: This is the main reason I made it. Surreal, silly or stupid depending on your sense of humour. Inserting blanks: Sometimes one wants gaps between tracks (for example so that one can run between a CD player & a dance floor when one is both dance teacher & DJ, as I have been at times, using an audio system without a remote control) and to have a track break marker between the gap and music track (so that one can skip the blank if needed).

To do that, just insert one of these silent tracks between each music track before recording.Fart Sound Effects - Wav Mp. You are allowed to use the sounds on our website free of charge and royalty free in your projects but you are NOT allowed to.I've had reports of these silent tracks being used for styles as varied as folk dancing, clubbing, zumba & yoga. Shutting up an irritating jukebox: If one wants peace & quiet but someone else keeps playing CDs on a jukebox or a CD player to which you have access, replace their CD with this one. It can similarly be used to shut up some irritating mobile telephones by converting a silent track to an MP3 and installing it as the ringtone. CD player noise test: It can be used to test a CD player, amplifier & speakers for background noise.
As there is no sound on the recording, any noise one hears from the system when playing this is noise added by the playing equipment. Practical joke: I had not intended it as a practical joke but found that one of my friends to whom I gave a silent CD tried playing it in a PC and assumed that the computer was failing when it gave no sound out (despite the CD being clearly labelled 'Silences'). He was going to waste time in a futile attempt to debug his music playing software.
To silence a CD player when using it as an amplifier: If one needs to use a CD player as a amplifier for an auxiliary input, such as from an MP3 player, but the amplifier only works with a CD playing then this can be used as a dummy CD to keep the CD player happy without producing unwanted sounds. (This use was invented by a reader of this site, Kane Zhu, who used it to fit an MP3 player to a car stereo system in addition to a CD player when the stereo's only external input was a dedicated CD player one.). To silence a smart phone when using it to output sound from apps: Several years later another reader similarly found that an iPhone would only push sound from a satnav application to a car hands-free speaker system when it was playing music and hence used a silent track as the music.

To see music player program animations uninfluenced by music: Some music playing computer programs display decorative animations that adapt to the music. To see what they look like when active but free-running without music to control them, play a silent track. Post navigation.
Is a free sound editing program that works well for preparing audio recordings for submission to eBird and the Macaulay Library. Continue on for a step-by-step demonstration of how to edit recordings for upload using this program.Ocenaudio is a destructive editing program, which means that if you edit a file and then use the “Save” function, the file will be permanently altered to reflect the changes that you made. To deal with this issue, the Macaulay Library recommends keeping two copies of your original sound files (one on your computer and another on an external hard drive), and then making edits to a third copy. With this approach, using the “Save” function will just make changes to a file that you have specifically designated for editing purposes. Editing a single sound fileIf you have a single sound recording that you’d like to upload to an eBird checklist, it can be prepared in just a few easy steps. Below is a single sound file, without any pauses, with four songs from a Western Meadowlark:The first step is to listen to the recording, find where the first sound from the target species occurs, and then highlight the three seconds immediately before that sound:Looking at the waveform of this recording, we see that the three seconds that are highlighted are “clean audio,” with no recordist noise or prominent, potentially confusing background species. In a case like this, you should include this three-second buffer of ambient sound in the final sound file that you upload to eBird.
But if there is any additional audio before the buffer, go ahead and delete it. In our Western Meadowlark recording, there are about three seconds of additional audio that we will delete:After trimming the beginning of your recording, go ahead and do the same thing at the end of your recording—look for the last sound from your target species, include a three-second buffer of ambient sound after that sound, and then trim any additional audio after the buffer.In some cases, it is not possible to create a clean three-second buffer immediately before the first target sound. In the sound file below, the target species, Lazuli Bunting, begins singing near the 4-second mark:However, loud handling noise caused by the recordist moving occurs shortly before the Lazuli Bunting song:If we included a three-second buffer in this case, the loud handling noise would prevent us from normalizing the recording. So, we will instead create a shorter buffer that ends immediately after the handling noise, creating a clean one-second buffer before the first Lazuli Bunting song:Returning to our Western Meadowlark example, we now have a sound file that looks like this:After trimming the ends of the sound file, the next step is to normalize the recording so that the loudest sound from your target species reaches a level of -3 dB. By setting the peak level of your recording to -3 dB, you’ll be creating a sound file that is consistent with the thousands of sound files archived in the same way at the Macaulay Library. This is very easy to do in Ocenaudio, which has a convenient “Normalize” command in the Effects menu, under “Amplitude”.
After normalizing the sound file to -3 dB, our Western Meadowlark recording looks like this:The final step is to save the changes that you have made to your sound file. Before pressing “Save,” though, make sure that you have backup copies of your original, unedited sound file.There are two other things to think about when you reach the point of saving your newly edited file: the name and audio properties of the file. Naming the file with the bird’s common name or scientific name can be helpful in identifying it as an edited file intended for upload (versus an original field recording), but ultimately, use whatever system works best for you. For the audio properties of your sound file, the best and easiest thing to do is to save your edited file with the same format, sample type, and format settings as your original field recording. The eBird upload tool can handle sound files up to 250 MB in size, so if you’ve recorded a.WAV file in the field, please upload an edited.WAV to your eBird checklist!
Multiple recordings of the same individual birdIf you made two or more field recordings of the same individual bird in the same location and at the same time, you should group these recordings together and create a single multi-part sound file for upload. Below is an example of two Louisiana Waterthrush recordings of the same individual, made in rapid succession: Louisiana Waterthrush 1 Louisiana Waterthrush 2Before grouping these two recordings together, the first step is to edit each individual segment following the guidelines in the “Editing a Single Sound File” instructions above.
First trim and normalize first sound file:Then perform the same actions on the second segment (and any additional segments):Because these two files are both recordings of the same individual Louisiana Waterthrush, they should be grouped together in a single file. To do this, add one second of silence to the end of “Louisiana Waterthrush 1” by placing the cursor at the end of that file, going to the Generate menu, selecting Silence, and typing a duration of “1”. Then highlight the second sound file, “Louisiana Waterthrush 2”, Select All, and Copy. Returning to the “Louisiana Waterthrush 1” file, place the cursor at the end of that file (after the one second of silence) and Paste the contents of “Louisiana Waterthrush 2” at the end. The final result is a single file with two segments separated by one second of silence. This silence allows a listener to know that there was a pause in the field between the creation of the first segment and the second segment of the recording. After adding the contents of the second file to the first file, Save and rename this composite file to differentiate it from the two individual source files.

Here is our final merged file:The end result is a single file with two separate segments, each trimmed and with the peak level set to -3 dB. This single new file is now ready to be uploaded to eBird! Recordings with voice announcementsWe encourage recordists to make voice announcements after recording a bird and to include these voice announcements with any recordings that are uploaded.
If you do include a voice announcement with a bird recording, simply add it to the end of the recording by following the “Multiple Recordings” guidelines above. There is just one difference in how we handle voice announcements—we only amplify the voice announcements to a peak level of -10 dB (rather than the -3 dB peak for bird sounds). Here is a completed sound file of a Northern Cardinal song with a voice announcement at the end:Now your recording is ready for upload to the Macaulay Library and eBird!
