Wav To Bwf Converter

Posted on 24.05.2020admin

BWF-O-Matic is a companion program to BWF-Widget Pro. While BWF-Widget Pro deals mainly with Metadata, BWF-O-Matic is designed to non-destructively slice and dice Broadcast Wav Files while maintaining all the metadata and Time Code from the original file. BWF is abbreviation of Broadcast Wave Format which is a file format for audio data and the updated version of WAV file, but what BWF really differs from WAV is BWF contains an extra 'chunk' to show the content information, like title, origination, date, time, etc. Is there a free Mac program to convert wav files to BWAV files? I could be wrong, but I think all you have to do is add the.bwf extention to your.wav file. I worked on a show that required broadcast wave and that's all we did. 4th December 2013. Welcome to the Gearslutz Pro Audio Community! Registration benefits include. BWF files are able to be read and edited in several different audio and video programs like Cakewalk and Final Cut Pro. If you would like to turn your WAV file into a BWF, it is possible to convert between the two formats.

Extended from	WAV
Standard	EBU - TECH 3285 Specification of the Broadcast Wave Format (BWF)

Broadcast Wave Format (BWF) is an extension of the popular Microsoft WAV audio format and is the recording format of most file-based non-lineardigital recorders used for motion picture, radio and television production. It was first specified by the European Broadcasting Union in 1997, and updated in 2001 and 2003.

The purpose of this file format is the addition of metadata to facilitate the seamless exchange of sound data between different computer platforms and applications. It specifies the format of metadata, allowing audio processing elements to identify themselves, document their activities, and supports timecode to enable synchronization with other recordings. This metadata is stored as extension chunks in a standard digital audio WAV file.

Files conforming to the Broadcast Wave specification have names ending with the file extension .WAV.

Details[edit]

In addition to the common WAVE chunks, the following extension chunks can appear in a Broadcast Wave file:^[1]

Original Bext chunk (Broadcast Extension - 'bext')
iXML chunk ('iXML')
Quality chunk ('qlty')
MPEG audio extension chunk ('mext')
Peak Envelope chunk ('levl')
link chunk ('link')
axml chunk ('axml')

Since the only difference between a BWF and a 'normal' WAV is the extended information in the file header (Bext-Chunk, Coding-History, etc..), a BWF does not require a special player for playback.

Unfortunately, this compatibility also preserves the filesize limitation that WAV files have (4 GB of audio data per data chunk).In order to be able to store audio which would exceed this limit, 2 different chunks exist allowing the audio material to be spread across several files: cont & link (see list above)

Since there is no official naming convention for these subsequent files, and it is still desirable to see at a glance which ones belong to a continuous piece of audio, a lot of programs apply a numbering scheme to the file suffix: .wav, .w01, .w02, .., .wNN.

Each of those segments is a regular Wave/BWF file, but players that are aware of the continue/link chunk will treat all segments as one single, long piece of audio when opening the first segment '.wav'.

As an extension, RF64 is a BWF-compatible multichannel file format enabling file sizes to exceed 4 GB that has been specified in 2006.

The axml chunk allows users to incorporate data compliant with the XML format with the audio; the chunk may contain data fragments from one or more schema.

On August 2012, the European Broadcasting Union published a specification for embedding International Standard Recording Code (ISRC) in the axml chunk of the Broadcast Wave Format.

BWF is specified for use in MXF by SMPTE standard 382.

Perhaps you are an assistant editor tasked with ingesting and syncing a batch of Broadcast Wave files recorded in the field. You try to sync by timecode, but you notice that each file has a different timecode offset. Then, on one particularly long take, you notice that the audio starts in sync, but slowly drifts out of sync.

Despite the best of workflow intentions, things go wrong: settings are misunderstood or mis-communicated; editing software is upgraded or changed. Stuff happens.

Fortunately, all does not have to be lost. Depending on what you need to edit, report or listen to in a batch of Broadcast Wave files, there is a utility for you! As you explore these utilities, please remember to test them on a COPY of your BWF files, and also please completely test all aspects of your workflow before commiting your entire production and post-production departments to them.

Here is a brief overview of the BWF utilities that we’ve found useful:

AVTransfer

http://www.avtransfer.net
Publisher: Fairlight
Price: $799.00
Platform: Windows
Works with: BWF Files from all records
Comments: This is the oldest BWF utility that we have worked with, and certainly many of it’s features have been replaced by some of the less expensive utilities listed below. It does, however, have one feature that is unique and useful: The ability to convert BWF files into OMF files for import into older Avid systems.

BWF Manager

http://www.fostexinternational.com/docs/pro_support/pro_bwf_manager.shtml
Publisher: Fostex
Price: Free!
Platform: Mac/Windows
Works with: BWF files from all recorders (up to 8 tracks)
Comments: Made for getting BWF files into or out of the Fostex DV40 and DV824, and works with files from all manufacturers. Useful for batch creating poly files if they were delivered in mono. It is also useful for splitting a large poly into mono files.

BWF Restamp Tool

http://www.24p.com/AvidInsider2.htm
Publisher: Michael Phillips
Price: Free!
Platform: Mac/Windows
Comments: This tool is for very specific Avid 24p workflows and manually adjusts the timestamp of BWF files to match the Avid’s default project settings. USE WITH CAUTION!

http://www.one-n.com/
Publisher: One-N Corporation
Price: $99.00 (each)
Platform: Mac/Windows
Works with: BWF files from any recorder, up to 24 tracks
Comments: Although pricey, this pair of utilities has a clean interface and gets the job of (you guessed it) splitting and combining BWF files in batch mode VERY quickly.

BWF Timecoder

http://www.one-n.com/
Publisher: One-N Corporation
Price: $99.00
Platform: Mac/Windows
Works with: BWF files from any recorder
Comments: This ingenious utility will create a SMPTE LTC track based on the timestamp of the BWF file. Perfect for transcription services that get BWF files from the field with no timecode track, and also for creating music video playback masters for non-BWF playback devices (e.g. Garageband, etc.) – simply plug the audio out into a timecode slate.

BWFWidget / BWFWidget Pro / BWF-O-Matic / BWF-D-Base

http://www.bwfwidget.com/
