![]() Old and new values of modifications are listed side by side for a comparision.Īll logged activity can be exported into comma separated text files for further processing in a spreadsheet or to be archived. You are able to build powerful exceptions like *.TMP, WRD?.DOC, *(?)*.TXT etcĪttribute Changer keeps track of modified and failed files and folders during processing.īy default, Attribute Changer displays failed actions in the Reporting tab, but a more detailed view can be activated at any time to display a complete view of all activities in realtime, such as successful and failed changes. Name filters are useful to exclude/include files and folders based on wildcard characters (* and ?). You can create different metadata presets for audio files. Ranges can be defined for date, time and size related criteria. When opening an audio file, audio montage, or batch process, the metadata found in the file is loaded. Powerful filters can be applied to include or exclude objects based on attributes, date, time, size and name wildcards. Redate folder with newest or oldest folder.Redate folder with newest or oldest file.Partial updates (for example only day or minute etc.).Modify or add photo date and time (EXIF).Add/Subtract values on day, month and year.Add/Subtract values on hour, minute and second.On photos, date and time information stored in the EXIF header can be easily altered or even added if missing.Ĭhoose among a set of powerful features to resolve issues about date and time modifications. Step 1: Download the WAV Editor As a starter, download and install the program on your computer by clicking the download buttons below. Powerful options are available to manipulate date and time stamps on files and folders. Files and folders can be hidden under normal conditions if the Hidden attribute is set.įor better readibility, Attribute Changer can be used to Capitalize, Uppercase or Lowercase filenames, foldernames and extensions. Much more powerful options include simulation, batch processing, randomization, synchronization among others.įor example, you can make a file Read-Only to prevent software programs from saving changes to a file. Filesystem attributes can be changed and you can uppercase, lowercase or capitalize names. You can also check out which I've never used, but it came up in a search.Attribute Changer can modify date and time on files, folders and photos. Ableton Live WAV Editor - Audacity Audacity is a free and open-source audio editing program, which is able to make audio editing easy and efficient. This article lists 5 best WAV editor software to you. I suspect libsndfile will work, but it doesn't have an MP3 reader, so maybe not. To edit a WAV format, you have to need one WAV editor for help. I don't know of a library that will read ID3 tags in WAV files in Java, so you'll either have to write one, or wrap one written in another language. To get to them, you'll need to understand WAV files first, at least enough to know what chunks are, chunkIds, how to skip chunks you don't care about, and so on. (on unix/macos I would use the "strings" command, maybe with "head") ID3 tags are standard for MP3, and you can figure out how to parse them by googling. You coud probably figure this out by searching for strings of length 4 or more in the file - usually data chunks are in the beginning and audio is at the end. I don't know for sure what the chunkID is for ID3, but it's probably "id3 ", or "ID3 " (including the space). well there's no standard chunk for that, so if that's really in the file, and not in the windows db somewhere, it's probably stored in ID3 tags embedded in the WAV. One of those chunks contains information like the samplerate, number of channels and total number of sample frames, from which you can calculate the length.įor artist, genre and so on. If the reader doesn't understand one of those chunks it is able to skip it, which allows placing a lot of different kinds of information in the file. ![]() ![]() To get durration information, see this link: Java - reading, manipulating and writing WAV filesĮssentially, a WAV file is broken up into chunks, which either contain audio data, or describe the audio data in some way, or provide information about it.
