CONSIDERATIONS FOR SOUND RECORDING
Define each sound format
WAV- A lossless, uncompressed format that is with high quality this allows it to be suitable for video and music production purposes. All recordings such as the zoom H4n will be set to wav automatically however it can be changed.
AIFF- An apple proprietary format and lossless. As with the wav format it is a lossless file type because it directly copies the original audio source.
FLAC- A compressed, lossless format and takes up a lot less space then a wav or aiff this has allowed it to become the most popular lossless format because it is open source.
MP3- Is the most common lossy format. many people use this file to store music on their smartphones as mp3 because it takes up a lot less space than a lossless file and it is supported by a range of websites.
AAC- A lossy format similar mp3. Apple iTunes have made this format popular and it shares nearly the same level of compatibility with devices as mp3.
Ogg Vorbis- An alternative to mp3 and AAC and open source its name comes from the Ogg container This is a popular lossless format because it is open source.
WMA- Microsoft's own proprietary format, similar to mp3 or AAC it does not really offer any advantage over the other formats and is also not as well supported in terms of sound production you would very rarely compress to this format
Storage
Digital drives can be used to store audio files. It's crucial to always have a backup copy of your work when creating audio. The project file must be saved in the same location as the raw audio files when importing audio data into any video software. After that, you can backup this information on:
Flash drive/USB: A Flash drive/USB is a standard interface that allows devices to communicate with a host controller, such as a personal computer (PC). It establishes connections between peripheral devices like flash drives, external hard drives, media players, mouse, keyboards, printers, scanners, and digital cameras. Flash drives have the advantages of being portable and multifunctional. They are also tough because they don't have any moving parts. They are also incredibly user-friendly and inexpensive. It is possible for a flash drive to become infected when it is linked to a computer that has malware, which increases the risk of data loss or corruption.
A computer's hard drive is a non-volatile hardware component that is used to store and permanently access data. Because a hard drive has a larger storage capacity, you can store more on it. When working with huge files, this is useful for maintaining free space on your PC or Mac. To safeguard your data in the event of a hard drive accident, you can also backup your computer to an external hard drive. Hard drives don't come with password protection, though. Anyone who plugs in your drive can access your data if you lose it. Your level of security is constrained by an external disc. Keep your drive in a secure location to prevent data theft.
A cloud drive is a web-based service that offers storage space on a distant server. Cloud backup services. The ability to view stored data from any location with an Internet connection is a benefit. Additionally, all of the cloud storage solutions examined in this article include desktop folders for PCs and Macs. Users can now drag and drop files between their local storage and the cloud storage as a result. However, there are issues with the security and privacy of sensitive data kept in faraway locations. Some businesses are concerned about the risk of private data being shared with other groups.
Compression
Compression is a method for modifying an image file's characteristics and reducing file sizes. These characteristics consist of file type, resolution, size, and bit depth. Examples of various compressions are:
Dynamic range compression (DRC): DRC is an audio signal processing technique that decreases the amplitude of loud sounds and increases the volume of quiet sounds, so lowering or compressing the dynamic range of an audio signal. This is beneficial for shrinking file sizes, which frees up more space on your device, but these loud noises can be required because they have a stronger impact.
The majority of compressors use "downward compression," which essentially results in the quietening of powerful noises. More exactly, signals over the threshold level are "squashed" by a quantity indicated by the ratio setting while signals below the threshold level are left alone.
Upward compression: In this technique, the louder parts are left alone while the quieter components are compressed. As a result, you won't be able to hear any necessary quieter sounds. However, this is preferable to downward compression, which tames powerful sounds that are necessary for the sound file's effect but makes them quieter.
Size versus quality
Lossy: Lossy file compression causes the original version to lose quality and some data. Lossy compression can be used for music files like MP3s or AAC files, but it is mainly linked with image files like JPEGs. Lostness in audio files can cause a watery sound or lessen the music's dynamic range. A benefit of a lossy file is that since lossy compression omits data from the source file, the final file frequently uses significantly less disc space than the source. Lossy files, however, degrade the original audio file's data and quality.
Lossless: After the file is uncompressed, every single piece of data that was initially present is still present. The information has been fully recovered. A benefit of lossless file compression is that it preserves the original file's quality. Lossy compression, on the other hand, shrinks a file by permanently removing some information, particularly redundant information. Upon file uncompressing, just a portion of the original data remains (although the user may not notice it).
Bit rates: The amount of data processed per second is indicated by a file's bit rate. Typically, bit rates are expressed in kilobits per second (kbps). File size, image quality, accessibility, and delivery costs can all be impacted by bit rates. As a result, if you want to alter the image quality or other factors, you can change your file format based on the bit rates.
A file's size is the amount of room it occupies on a storage device, like a computer hard drive. As a result, you can see how much space the file occupies on your device.
