Part 1: Why Increase M4A Volume?

M4A (short for MPEG-4 Audio) is a proprietary audio file format Apple created for its ecosystem. Think of it as Apple's answer to the more popular MP3 format, albeit with superior audio quality and compression. M4A's unique advantages make it suitable across a broad set of use cases, especially for audio streaming. Naturally, services like iTunes use this format extensively. Whenever you save a song or podcast on iTunes, it's stored in M4A on the device. And, Apple exercises complete control over the quality settings of the M4A files, including audio volume.

Apple deliberately limits the audio volume on M4A files to a certain level for several reasons. For one, they do this to ensure that the audio levels are not so abnormally high that they cause irreparable hearing damage to users. Secondly, consistent volume across platforms ensures consistency in the listening experience, which is desired by both Apple and music producers. Thirdly, audio playback at high volume is a significant drain on the battery and also increases data usage when you're streaming.

When you find the max volume of your M4A content highly limiting, you have to increase M4A volume at the file level. Beware: this may often lead to audio distortion, resulting in poor listening experience.

Method 3: Permanent Volume Booster for M4A Files: Audacity

Audacity is another tool like HitPaw Online Volume Changer to permanently increase volume of M4A files. One crucial difference between the two is that Audacity is a desktop tool. It's also the industry standard for audio editing. This means it's loaded with features and tools that can overwhelm new users. For beginners and intermedial level users, HitPaw Online is a better choice. But if you're comfortable around full-fledged audio editors, Audacity can be a great tool. Here's how you can permanently boost the volume of M4A files in Audacity:

Step 1: Install and launch Audacity >> Go to 'File' >> Choose 'Open' >> Select and import the M4A file into Audacity.
Step 2: Select the entire track >> Go to 'Effect' in the Main Menu >> Choose Amplify >> Adjust the settings to suit your volume requirement >> Click on 'Preview' to review the outcome >> Hit 'OK' when you're done.
Step 3: Go to 'File' >> Choose 'Export Audio' >> Choose export settings >> Hit 'Export.'

Method 4: Temporary Volume Booster for M4A Files: VLC Media Player

Even during regular playback, VLC Media Player goes above 100% of an audio or video file's volume level. With the right configuration, VLC can push the volume to 300% of its original limit. It will require some customization, so follow these steps accurately:

Step 1: Launch VLC Media Player >> Go to 'Tools' in the Main Menu >> Choose 'Preferences.'
Step 2: In the Advanced Preferences window, click 'All' under Show Settings in the left bottom corner >> Check the 'Only show current' checkbox at the top left corner >> Choose 'Qt.'
Step 3: In the Qt Interface panel on the right, scroll down until you find 'Maximum Volume displayed' >> Set it to any value up to 300. For reference, a value of 200 increases the maximum volume by 2X.
Step 4: Click 'Save' >> Play any M4A file at boosted volume.

This method does not make changes to the M4A file permanently. The maximum volume level is changed only for playback with VLC Media Player. If you play the files on any other media player, the default maximum volume settings will still apply. For more permanent results, choose a tool like HitPaw Online Volume Changer or Audacity, which boosts volume at the file level so that the maximum volume level remains altered no matter which media player or device you're using.
