What's the best way to convert MP3 to FLAC on Windows 11?

I previously sought to convert MP3 to FLAC. Although I understand that converting MP3 to FLAC does not enhance sound quality, organizing the music library and ensuring device compatibility were my primary motivations. In this context, I explored several methods and now share my genuine experience with you.

Method 1: Use Audaity
Audaity is a free, open-source audio editing software with robust features. It supports converting audio between multiple formats, including MP3 to FLAC. The process is as follows:

1. Download and install Audaity from the official website (safe and ad-free).
2. Open the software and drag the MP3 file into the main interface.
3. Click "File > Export > Export as FLAC" to set parameters such as sampling rate (44.1 kHz recommended) and bit depth (16-bit recommended, consistent with the original file).
4. After conversion, the FLAC file will be saved to the specified location.

Features:
- Audaty allows for custom output parameters, making it suitable for users who need to adjust audio quality.
- It provides manual tag editing, which is ideal for processing a small number of files.
- Free and safe, appropriate for users with basic audio processing knowledge.
Applicable scenarios: If you need to adjust audio parameters or process a small number of files, Audaity is an ideal choice.

Method 2: Use XRECODE
XRECODE is a tool specifically designed for audio format conversion, particularly suited for batch conversion of MP3 to FLAC. The operation is straightforward:

1. Download and install XRECODE (compatible with Windows, simple interface).
2. Open the software and drag all the MP3 files you want to convert into the list.
3. Select FLAC as the output format in the lower right corner and set parameters such as sample rate and bit rate.
4. Click the "Start" button; the software will quickly complete the conversion while retaining original audio tags and album art.

Features:
- Supports batch conversion, extremely fast, even hundreds of songs can be processed quickly.
- Automatically retains tag information (such as song name, album name, cover art), eliminating the need for manual settings.
- A free trial version is available, but there is a limit on the number of files; the paid version is a one-time purchase, suitable for long-term use.
Applicable scenarios: If you have a large number of MP3 files that need to be converted to FLAC and require the tags to be preserved and processed efficiently, XRECODE is highly recommended.

Features:
- No need to install software, conversion can be completed directly through the browser, making it very convenient.
- Supports simple parameter settings, suitable for users without technical knowledge.
- The free version has limits on daily file size and number, making it suitable for small batch file conversion.

Summary:
- Audaty: Free, flexible, suitable for users with a small number of files and those who need to adjust audio parameters.
