Again depending on the source material, variable or fixed bitrate produce different results. For example speech or a live recording of a rock band can survive a lot more quality loss than a recording of a string quartet. Depending on the complexity of the source material, it's possible that the loss of quality in the end result is humanly undetectable, excluding professional mastering (and some mixing) engineers. The loss can be minimized by converting with highest quality, but not completely avoided. Further reduction in the file size is achieved by compression. The discarded information will be permanently removed, causing the loss of quality. MP3 conversion algorithm passes the audio through psychoacoustic modeling, which utilizes auditory masking to determine what parts of the audio must be kept, which can be discarded to reduce the file size. The audio can usually be exported directly as MP3 from the application, in which case the conversion happens during the export process, or the saved lossless file can be converted afterwards. If the resulting file must be in MP3 format, it must be converted. The waveforms of both the channels (left. Ocenaudio is a free audio editor that’s as accessible as they come. The file can usually be encoded also as AIFF (MacOS-only applications tend to default to this) or AU or it can be saved as a raw PCM data with no encoding.įiles can also be often directly saved is a compressed, lossless format such as FLAC, ATRAC, ALAC (MP4) or WMA Lossless (Windows Media Audio). How to convert stereo to mono in ocenaudio: Launch this converter and use the open option to load stereo audio in it. To ensure these files can be post-processed, all audio applications save the files in a uncompressed, lossless format, most commonly encoded as a WAV. The application can split the stereo channel to separate mono channels, which can then be saved to 2 new files. When the source file is opened in an audio application, any encoding disappears, it's simply raw audio data. My weapon of choice for this kind of quick work is Ocenaudio (a shameless plug *). Simply open the file on any audio application, split the stereo to 2 mono channels and save the channel with the audio to a new file. You can click the Custom Profile icon to adjust the profile settings. Step 2: Set mono as the audio channel Next, go to the Convert All to area and click the drop-down arrow to select the output format. If the end result can be WAV, AIC, ALAC, FLAC or any other lossless format, then yes, easily. Locate in Converter tab and click Add Files button to add all stereo music into the library area on the main window. There's no escaping that MP3 is a lossy file format.
