When multiple audio formats such as MP3 and M4A coexist in a folder, converting them one by one to OGG takes a lot of time. This article uses HeSoft Doc Batch Tool as an example to explain how to use the audio tool in office software to select "Convert Audio to OGG," and then use the method of adding files or importing files from a folder to create a batch task. The article illustrates the final effect with before-and-after file screenshots, and provides instructions on verification records, setting save locations, starting processing, and precautions to help users efficiently complete the conversion of multiple audio files to OGG.
Many users encounter a similar issue when organizing audio materials: a folder has accumulated many audio files, with the first few in MP3 and the later ones in M4A, but the project requires a uniform OGG format. If converting only one or two files, using ordinary audio tools is acceptable; but when the number of files increases, manually selecting each one, setting the format individually, and exporting them one by one becomes obvious repetitive labor. This article will explain "how to convert multiple audio files to OGG at once," helping you use HeSoft Doc Batch Tool to complete batch audio to OGG conversion.
This software is a batch processing tool for office files. Besides common document processing, it also provides a category for audio tools. For office users, the real value lies not in a single conversion, but in placing a batch of files into the same workflow for unified processing. This reduces repetitive clicking and makes conversion results more standardized, especially suitable for teams or individuals who need to manage large amounts of audio materials.
Applicable Scenarios: From Scattered Audio to Unified OGG Files
The OGG format is often used for web playback, application resource packages, audio material delivery, and certain development projects. In actual work, the sources of audio files can be very mixed: recording software exports M4A, historical materials are in MP3, and other formats are generated during editing. If OGG delivery is ultimately required, a format unification must be performed.
Batch conversion to OGG is suitable for the following types of users: first, content teams that need to uniformly deliver course dubbing, notification sounds, and background music to technical staff; second, operations, design, and development collaborators who need to organize audio resources for websites or applications; third, office users who wish to uniformly archive historical MP3 and M4A materials into OGG; fourth, people who frequently process audio files but do not want to waste time on repetitive operations.
The benefit of using a batch processing tool is that you do not need to repeat the same actions for each audio file. Simply select the function, import files, confirm the list, and follow the process to get uniform output results.
Effect Preview: Non-uniform Audio Formats Before Conversion
In the pre-processing screenshot, eight audio files can be seen in the file list. The first items have the .mp3 file extension, and the later items have the .m4a extension. Although their naming convention is relatively uniform, all being "Audio test" plus a number, the formats are inconsistent. The size column on the right shows different file volumes, which is consistent with multiple independent audio materials mixed in the same directory.
In this state, if you need to deliver to a platform or project that only accepts the OGG format, format conversion must be performed first. Using traditional methods to process them one by one not only involves repetitive steps but also makes it difficult to ensure all files are correctly converted. The core problem before processing is: a large number of files with mixed formats need to be uniformly output as OGG.
Effect Preview: All File Extensions Are OGG After Conversion
In the post-processing screenshot, the same batch of files is now all displayed with the .ogg extension, clearly arranged from "Audio test 1.ogg" to "Audio test 8.ogg". The file sizes on the right have also changed compared to before processing, indicating that new OGG audio files were generated. For subsequent uploading, calling, or archiving, a folder with a unified format is easier to manage.
Note that the goal of batch conversion to OGG is not to make file names look consistent, but to ensure the audio format truly meets OGG requirements. The change in file size after processing is a normal result of changes in audio encoding and packaging.
Step One: Find the Audio Tool on the Left Side
After launching HeSoft Doc Batch Tool , first observe the function navigation on the left. The screenshot shows the software is categorized by file type and office tasks, including Word tools, Excel tools, PowerPoint tools, PDF tools, Text tools, Image tools, Video tools, and Audio tools. Our current goal is to process audio files, so we need to click "Audio Tools" on the left.
After entering the Audio Tools, the main area displays several audio format conversion function cards. The software separates different target formats into clear entry points, such as converting to MP3, AAC, M4A, WMA, WAV, FLAC, OGG, OPUS, etc. This design prevents users from searching for the target format among complex parameters, allowing them to directly choose the desired conversion direction.
Among these options, select "Convert Audio to OGG". In the screenshot, this card is highlighted, indicating it is the function entry to be used in this tutorial. After selecting it, the software will enter the dedicated batch OGG conversion process.
Step Two: Import the MP3, M4A Audio Files to be Converted
After entering the "Convert Audio to OGG" page, the interface provides two main import buttons at the top: "Add Files" and "Import Files from Folder". Their usage logic is intuitive: if you only want to select some audio files, use "Add Files"; if the audio files to be converted are concentrated in the same folder, using "Import Files from Folder" is more convenient.
From the screenshot, you can see that imported files are displayed in a table format. The table columns include information such as sequence number, name, path, extension, creation time, modification time, and actions. For batch tasks, this list is very important because it serves as a confirmation checklist before conversion. You can check whether all necessary files are included and view the extension column to confirm that both MP3 and M4A files are in the task.
In the example, a total of 8 records were imported. The extension column shows mp3 for the first files and m4a for the later ones. The summary area at the bottom also shows a record count of 8. This indicates the software is ready to perform batch processing on these files.
Step Three: Check the List and Remove Unnecessary Records
Before batch conversion, it is recommended not to skip the verification step. Because once the batch task starts, all files in the list will be processed according to the same rules. If audio files that do not need conversion are imported by mistake, they may generate extra files, increasing subsequent organization costs.
In the "Actions" column of the current interface, each record has a corresponding delete icon. If you find a file is not needed for this task, you can remove it first. For situations with many files, "Filter" and "Sort" buttons are available on the interface to help view and organize the list. Although this article focuses on audio to OGG, managing records before conversion also impacts final efficiency.
After confirming the file names, paths, extensions, and quantities are correct, click "Next Step" at the bottom. The expected result of this step is to enter the subsequent setup process, not immediate conversion. The software's top process steps show Step 1 as "Select records to process", Step 2 as "Set save location", and Step 3 as "Start processing", so users can complete tasks in order.
Step Four: Set the Output Location and Start Conversion
After entering "Set save location", you need to determine the save directory for the OGG files. It is recommended to place the converted files in a separate folder, for instance, creating a new "OGG Output" folder next to the original material directory, which prevents mixing them with the original MP3 and M4A files. For team collaboration, you can also directly choose the project's agreed delivery directory to reduce subsequent file moving steps.
After setting, proceed to "Start processing". Since "Convert Audio to OGG" was selected earlier, the software will perform batch conversion on the audio files in the imported list according to this function. The user just needs to wait for the processing to complete and then check the results in the save location.
After completion, if the files all have the .ogg extension and the quantity matches the task list, it indicates the batch conversion is done. Combined with the post-processing screenshot in this article, you can see that all 8 source audio files ultimately got their corresponding OGG files.
Frequently Asked Questions and Notes
1. Can multiple audio formats be placed in the same task? From the example screenshot, you can see the task list contains files with both mp3 and m4a extensions, and the final target is OGG. Therefore, in similar scenarios, these audio files can be imported together for batch conversion.
2. Should I use Add Files or Import Files from Folder? If files are scattered, "Add Files" is more flexible; if files are concentrated in one directory, "Import Files from Folder" is more suitable for batch office processing, saving time on repeatedly selecting files.
3. Why does the file size change after conversion? Audio format conversion involves changes in encoding and packaging, so it is normal that the generated OGG file size is not completely identical to the original MP3 or M4A. The post-processing screenshot also shows changes in file size.
4. How to confirm no files were missed? Check the record count at the bottom of the task list before conversion, and verify the number of OGG files in the output directory after conversion. In the example, the record count before conversion was 8, so 8 OGG files should be obtained after processing.
5. Do I need to keep the original audio? It is recommended to keep them. Although batch processing is efficient, the original files are important material sources. Outputting OGG files to a new directory allows retaining both the source files and the conversion results.
Summary
The key to converting multiple audio files to OGG at once is to choose office software that supports batch tasks and follow the workflow of importing, checking, setting the save location, and starting processing. HeSoft Doc Batch Tool uses the "Convert Audio to OGG" function within "Audio Tools" to bring MP3, M4A, and other audio formats into the same conversion task, reducing the repetitive labor of individual processing.
