Frequently Asked Questions
Here are some common questions and answers about gsm file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
Q: Is there a limit to how big my audio file can be?
A: While we support large files, it's always a good idea to keep your audio file under 200MB to ensure a smooth conversion. Large files might take a little longer, but don't worry—RunConvert will handle it!
Q: How do I convert a mixed-format audio file?
A: If you have a mixed-format file (like one with both music and speech), you’ll need to extract the individual elements first. Then, you can upload each file separately and convert it to the format you need.
Q: Can I convert multiple audio formats at once?
A: Yes! You can batch upload and convert multiple audio files at once with RunConvert. It’s a huge time-saver if you’ve got a lot of audio files to deal with!
Q: What’s the fastest way to convert a large audio file?
A: To speed things up, make sure the file isn’t too large before uploading. RunConvert can handle big files, but keeping them under 200MB will ensure quicker conversions. Otherwise, just be patient—it’ll be worth it!
Q: Can I convert music files to different bitrates?
A: Yes! If you're looking for a specific bitrate, we can help you convert your music files to match. It’s all about optimizing sound and file size to fit your needs.
Q: Can I convert audio files for streaming purposes?
A: Yep! Whether you’re preparing audio for Spotify, YouTube, or a podcast platform, RunConvert can help you get your audio into the right format. Most platforms prefer MP3, but we can handle a variety of options.
Q: What if my audio file is corrupted?
A: If your audio file is corrupted, it might not convert properly. Sometimes files get damaged during download or transfer. Try opening it on your device first—if it plays, you should be good to go. Otherwise, it might need some repair before conversion.
Q: Can I convert a podcast episode into a ringtone?
A: Yes, you can! If you have a favorite segment from a podcast episode, you can convert that portion into a ringtone format. Just trim the segment before uploading it and convert it into MP3 or M4R for iPhones.
Q: Can I convert an audio file to a specific sample rate?
A: While RunConvert doesn’t currently allow you to select a specific sample rate, you can use an audio editor to adjust it before conversion. After that, uploading to our platform for format conversion will be a breeze!
Q: Do I need an account to convert audio files?
A: Nope! You don’t need an account to start converting your audio files with RunConvert. Just upload, convert, and download—easy as that. However, creating an account might give you access to some cool features like conversion history.
What is GSM (Global System for Mobile Communications Audio)?
GSM (Global System for Mobile Communications Audio) is a specialized audio format developed for mobile telephony. It's a highly compressed format designed specifically for encoding speech at very low bitrates, typically 13 kbps, making it ideal for efficient transmission over cellular networks. GSM files use the .gsm extension.
The GSM audio format prioritizes intelligibility of speech over audio fidelity, using a compression algorithm optimized for human voice frequencies. This results in very small file sizes but with limited frequency response and noticeable artifacts for non-speech audio. Despite its limitations, GSM remains relevant in telecommunications and legacy voice messaging systems.
How to open GSM?
Opening GSM files requires specialized software due to the format's specific purpose in telecommunications. Media players like VLC can handle GSM files with the right codecs installed. For professionals working with telephony systems, specialized tools like Audacity (with GSM plugin) or SOX (Sound eXchange) offer GSM support.
Due to the specialized nature of GSM audio, converting these files to more common formats like WAV or MP3 is often the most practical approach for general use. If you're working with GSM files for telecommunications development or analysis, consider using dedicated telecommunications software that specifically supports GSM audio processing.
GSM is Developed by: European Telecommunications Standards Institute (ETSI)
GSM was Released on: 1991

How to convert GSM?
Converting GSM files is straightforward with our specialized audio converter. Whether you need to transform these telecom-specific audio files to standard formats like WAV or MP3 for broader compatibility, or to other speech-optimized formats, our tool handles the conversion process efficiently.
Our GSM converter maintains the intelligibility of speech content while transforming it into more universally playable formats. It's important to note that due to GSM's limited audio quality and narrow frequency range, the converted audio will retain these characteristics. For telecommunications professionals, we offer batch processing options to handle multiple GSM files simultaneously.
