Typically, to convert stereo to mono, I would load up the audio files, one by one, into my favorite free audio editor Audacityand take it from there. But the obvious problem with this approach when you need to transform multiple files is that it can be very time consuming.

Instead, I needed to find a software that can do this quickly and in batch. This post will show how to do this using FREE software. But first, a bit of background: I recently downloaded some thirty spoken word audio files that I was eager to listen to, only to discover that the audio swung left and right across my headphones uncomfortably. This seemed like it was an accidental or a mistake in the process of recording the files, and in any case I needed to find some way to convert the messed up stereo into a steady, more comfortable to listen to mono audio files.

Symmetrical drawing software Lisa Dawson - Jun 5, 1. Popular Posts.The WAV format is arguably the most basic of sound formats out there. It was developed by Microsoft and IBM, and it is rather loosely defined. As a result, there are a lot of WAV files out there that theoretically should not work, but somehow do. WAV files are usually stored uncompressed, which means that they can get quite large, but they cannot exceed 4 gigabytes due to the fact that the file size header field is a bit unsigned integer 32 bit file length means a maximum of 4 gigs.

WAV files are stored in a binary format. They are comprised of chunkswhere each chunk tells you something about the data in the file. Here are a couple of quick links that describe the WAV file format in detail. If you are doing work with the WAV format, you should bookmark these:. A chunk is used to represent certain metadata or actual data regarding the file.

Each chunk serves a specific purpose and is structured very specifically order matters. Note : There are a lot of available chunks that you can use to accomplish different things, but not all of them are required to be in a wave file.

Here is what the header looks like:. The Format chunk is the metadata chunk. It specifies many of the things we talked about in part 1 of this seriessuch as the sample rate, bit depth, number of channels, and more. As I mentioned, this chunk gives you pretty much everything you need to specify the wave format. When we look at DirectSound later, we will see the same fields to describe the wave format. The data chunk is really simple. Depending on your chosen bit depth, the data type of the array will vary.

The range of each of these elements is important too. Writing the wave file is as easy as constructing the Header, Format Chunk and Data Chunk and writing them in binary fashion to a file in that order. There are a couple of caveats. Firstly, determining the dwChunkSize for the format and data chunks can be weird because you have to sum up the byte count for each field and then use that result as your chunk size. You can do this by using the.

This value is equal to the total size in bytes of the entire file minus 8 including those fields that are ignored when calculating chunk size, such as sGroupID and dwChunkSize. The best way to accomplish all these things effectively is to implement a structure or class for the header and the two chunks, which have all the fields defined properly with the data types shown above.

Assign that value to dwFileLength and you are golden. What, no example code? I know, I know. Skip to main content.Unreal Engine 4's audio system provides tools and features to mold the sounds in the game to give them the desired feel.

This all starts with your audio source files. Either as mono or stereo files, they can be quickly imported into Unreal Editor 4 and begin breathing more life into your creations.

Below are the basic requirements for your audio content and a quick import guide. The engine currently supports importing uncompressed little endian 16 bit wave files at any sample rate although sample rates of Hz or Hz are recommended. Importing with the normal sound factory yields a simple sound node wave that can be referenced by a sound cue for playback. These sounds can be mono or stereo. Importing with a special naming convention gives the potential of multichannel e.

Up to 8 channel sounds can be compressed on all platforms, although not all platforms can play them back efficiently. The package saving process does all the necessary work to convert to the platform's native format. There is no strict speaker mapping, so the number of channels infers which channels are played on which speakers see table below. Compression settings are tweaked to maintain similar quality across platforms.

After testing many sounds, our musician determined an XMA quality of 40 was equivalent to an ogg vorbis quality of 0. From the Content Browser, click the Import button pictured below. Exporting a multi channel sound asset will create a mono. WAV file for each channel with the above speaker extension naming convention.

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

You can also extract the audio track of a file to WAV if you upload a video. In order to continue you need to upgrade your account:. We are constantly improving our service. Right now we support over 20 input formats to convert to WAV. They contain sounds such as effects, music, and voice recordings.

The Wave function is from tuneR which is one choice for audio in R, please refer to its help for details on the functions. The example above takes stereo wav audio, makes it mono and normalises the volume so that it will work through the API, as an example, but it will depend on your audio file and how it is recorded and encoded on what will work for you. Wave Object Number of Samples: Duration seconds : 4. Glad its working. For my test file, the stereo file was arranged that left channel was the first half of the file, the right channel was the second half, so I had to split them and rebuild, then turn to mono.

Its tricky to give one definitive answer as sound files are recorded in lots of different formats. Not through R, I use audio programs such as Audacity to manipulate audio files generally though, probably easiest way.

But I don't want to do that manualy I think you need to listen to the file and see if your processing did something weird. I don't know much about audio processing in R since I usually use an audio editor, you may have a more knowledge answer if you ask on tuneR 's issue thread I am interested too.

For the purposes of this document, only a simple PCM file will be explored. A WAV file contains a header and the raw data, in time format.

What's bit size? Bit size determines how much information can be stored in a file. For most of today's purposes, bit size should be 16 bit.

Bit size deals with amplitude. In 8 bit recordings, a total of 0 to amplitude levels are available. In 16 bit, a total of 65, to amplitude levels are available. The greater the resolution of the file is, the greater the realistic dynamic range of the file.

CD-Audio uses 16 bit samples. What is Sample Rate? Sample rate is the number of samples per second. CD-Audio has a sample rate of 44, This means that 1 second of audio has 44, samples. DAT tapes have a sample rate of 48, What are Channels?

Channels are the number of separate recording elements in the data. For a real quick example, one channel is mono and two channels are stereo. In this document, both single and dual channel recordings will be discussed. What is the data? The data is the individual samples. An individual sample is the bit size times the number of channels. For example, a monaural single channeleight bit recording has an individual sample size of 8 bits. A monaural sixteen-bit recording has an individual sample size of 16 bits.

A stereo sixteen-bit recording has an individual sample size of 32 bits. Samples are placed end-to-end to form the data. So, for example, if you have four samples s1, s2, s3, s4 then the data would look like: s1s2s3s4.Privacy Terms.

I've looked at some of the posts on here and followed the advice regarding usption the various options of setting the format to WAV microsoft and selecting the ULaw encoding but sadly it still doesn't work. Any ideas please? The exported file is always at the same sample rate as the "Project Rate" lower left corner of the main Audacity window. Set the Project Rate to before you export.
