MP3 Metadata Extraction REST API and Java SDK

I will be using the Java SDK of GroupDocs.Metadata Cloud API for extracting metadata of MP3 audio files. It allows you to add, edit, retrieve, and remove metadata properties from over 60 types of documents, images, and multimedia file formats. You just need to define the search criteria and the API will take care of the specified metadata operations within supported file formats. The API works with the most notable metadata standards such as built-in, XMP, EXIF, IPTC, Image Resource Blocks, ID3, and custom metadata properties. It also provides .NET SDK as its document metadata manipulation family members for the Cloud API.

You can easily use GroupDocs.Metadata Cloud in your Maven-based Java applications by adding the following pom.xml configuration.

<repository>
    <id>groupdocs-artifact-repository</id>
    <name>GroupDocs Artifact Repository</name>
    <url>http://repository.groupdocs.cloud/repo</url>
</repository>

<dependency>
    <groupId>com.groupdocs</groupId>
    <artifactId>groupdocs-metadata-cloud</artifactId>
    <version>20.4</version>
    <scope>compile</scope>
</dependency>

Please get your Client ID and Secret from the dashboard before following the mentioned steps. Once you have your ID and secret, add in the code as shown below:

Extract Metadata of MP3 Files using REST API in Java

You can easily extract metadata of MP3 audio files by following the simple steps given below:

  1. Upload the MP3 file to the Cloud

Metadata Extraction by Matching Exact Phrase using Java

You can extract the metadata property of MP3 files matching the exact phrase by following the steps given below:

  • Create an instance of MetadataApi
  • Create an instance of the MatchOptions and set ExactPhrase to true
  • Initialize an instance of the NameOptions
  • Provide value to match and set MatchOptions
  • Create an instance of the SearchCriteria and set NameOptions
  • Create an instance of the FileInfo
  • Set the MP3 file path
  • Create an instance of the ExtractOptions
  • Assign the defined SearchCriteria and FileInfo to the ExtractOptions
  • Create the ExtractRequest
  • Call the MetadataApi.extract() method and get results

The following code sample shows how to extract metadata by matching exact phrase using a REST API.

MimeType: audio/mpeg

Metadata Extraction by Regular Expression using Java

You can define search criteria to extract the metadata of MP3 files using the regular expression by following the steps given below:

  • Create an instance of the MetadataApi
  • Initialize an instance of the MatchOptions and set IsRegex to true
  • Create an instance of the NameOptions
  • Provide regular expression and set MatchOptions
  • Create an instance of the SearchCriteria and set NameOptions
  • Create an instance of the FileInfo
  • Set the MP3 file path
  • Create an instance of the ExtractOptions
  • Assign the defined SearchCriteria and FileInfo to the ExtractOptions
  • Create the ExtractRequest
  • Call the MetadataApi.extract() method and get results

The following code sample shows how to extract metadata searching by regular expression using a REST API.
