note: Mp3 Frame Remover is a simplified version of Mp3 Frame Editor, specialized in mp3 trimming

Do you get irritated by mp3's with pauses or noise on their beginnings and ends? Do you have mp3's downloaded from the web but they start with a 5 seconds pause and end with a 10 seconds pause followed by a loud "click"? You could convert them to wav, then edit using an ordinary sound editor, and compress to mp3 again. Not only that this process takes time, but it also reduces the sound quality (because quality is lost when you save the sound as mp3, just like when you transfer a bitmap image to jpg, for instance).
Maybe your problems are solved now. This mp3 trimmer can remove specified number of (milli)seconds from the beginning and end of a mp3 file (trim it).

Program limitations
It can edit only 32, 44.1 and 48 KHz, mono and stereo mp3's. However, this shouldn't concern you too much, if you plan to edit songs. I have several thousand songs in mp3 form, and they all meet these criteria. You can't run multiple instances of mp3 Frame Remover.

How to get it
Mp3 Frame Remover is cheap shareware. For just $15 you get 3 of my audio utilities: this one, Mp3 Frame Editor (more complex program for no-decoding-encoding editing of mp3 files, not just trimming), and Mp3 List Maker De Luhe (my other handy utility to help you manage your mp3 files). You can download the free version from the bottom of this page (it will work just like the registered one, but it will expire after 50 "save as" button clicks). To register follow the link at the bottom of the page.

A brief illustrated explanation of program's functions

mp3 trimmer main window

File and play
Use file menu or buttons to load or save a file or files. Batch processing begins if you select multiple files in open dialog box. Closing a file is not necessary, but may be performed. Reload loads the file last loaded (resetting all values to initial states). Play menu or buttons can be used to play loaded file, saved file, preview, or multiple loaded or saved files. Note that mp3 Frame Remover doesn't play the mp3's itself, it just calls registered mp3 player, like when you click an mp3 filename in Windows explorer.

1) On error: what do you want the program to do when it encounters mp3 file not formatted by the book (fail, prompt, or attempt to continue). 2) Save style: how do you want files saved as (offer save dialog every time, or append (1) or .trimmed to the filename). 3) Method of multiple files play (multiple parameter call of registered player or write a temporary m3u list and open it; both should work - if one doesn't, try the other) .4) Automatically check remove RIFF header & unknown header & footer: yes or no (recommended: yes). 5) Include subfolders in folder drag & drop operations: yes or no (left to your taste).

Beginning and end frames
You have 4 methods of determining trimming time. First, manual trimming: type a desired value into a textbox, time on the beginning in the left, and time on the end in the right one. Typing a value into a textbox automatically marks the method as "manual". Then there are methods 1, 2, and 3: automatic silence detection methods, ranging from almost 100% safe method 1 to highly unsafe method 3 that you use only if you don't get results with previous methods. Detailed explanations of these methods can be viewed if you click nearby "?" buttons. "Auto-use next time" checkboxes will make the program use the same method next time you load a file. Note: you should uncheck all if you want to manually type a different value every time. Checking auto-use checkbox on manual method will make mp3 Frame Remover not reset the typed value when you load a new file. Finally, you have the option to leave some silence, which is certainly advised. Recommended number is displayed. Total amount to be trimmed from the file's beginning or end is displayed at the bottom of each frame. It's calculated as the number from the top textbox minus leave silence [s].

Leave silence method
1) Just leave silence: for instance, if you mark 1 sec silence and specify leave silence value of 0.5 sec, 0.5 seconds will be trimmed. If leave silence value is larger than silence, no trimming will occur. 2) Add artificial silence up to specified number of frames: same, only if leave silence value is larger than silence, opposite of trimming will occur: empty (silence) frames will be inserted into the output file. 3) Delete all detected silence, then add artificial silence: first value specified as silence will be trimmed, and then empty (silence) frames will be inserted (specified by leave silence value).

Non-audio data removal
You have 4 known tags (id3v1, id3v2, lyrics3, and RIFF) to view or remove. There are also other types of tags or non-audio data near the beginning or end of the file that can be viewed or removed using right two buttons and checkboxes (unknown header or footer data). You will probably want to clear your files of unknown origin data and RIFF headers. This is especially important if you want proper VBR seek header to be saved in case of VBR files with unknown origin data near the file beginning (unknown header). mp3 Frame Remover re-creates VBR seek header (Xing format) of VBR files. mp3 Frame Remover always removes such headers from CBR (constant bitrate) files.

You can use this application to "open files with" from Windows Explorer. Drag & drop operations are allowed both onto program icon (starts the program) and onto program main window (closes previously loaded file[s] and opens new one[s]). Multiple files and folders drag & drop operations are allowed, and subfolders may be processed if specified by options.
Unicode 8 and 16 bit characters are supported so the application should work with the majority of world's languages.

Starting from Windows 8, Microsoft tries to put small vendors out of business by blocking their applications with SmartScreen (unless, of course, they pay for the certificate). If you get this message, you have to click More info and then Run anyway. Even then, the User Account Control window will pop up asking you if you want to allow the application to make changes to your computer. You must answer Yes in order to install the program.
If you have any doubts about the credibility of the publisher, this program has been around since the early 00's, and is listed at a considerable number of shareware listing sites. This can be verified by a Google query.
