Tutorial Selecting an Optimal Recording Format, Total Recorder. Tutorial Selecting an Optimal Recording Format. This tutorial provides recommendations on how to select the optimal recording format and attributes in Total Recorder. The quality of digital sound is determined by discrete parameters and by compression parameters. Discrete parameters are the sample rate, bit capacity, and the number of channels. Compression parameters are the compression format being used and the bit rate. General recommendations for selecting a recording format Sometimes the recording format is determined based on how the target file will be used. Also, it is not feasible to choose a target sound format with a higher quality than the source sound format. This only leads to an increase in the size of the target file. In other cases, the optimal recording format depends upon the type of recording e. Below are some recommendations that you can consider when selecting an optimal format for your recording.

Selecting the recording format for Sound board recording. If you record from some external device including. CD or LP player you need to use Sound Board. When recording from digital input lines, you need to match the recording format sample rate with the format of the sound source. Sometimes you will need an exact match of the source sample rate and recording sample rate. To determine the required sample frequency, use menu Options Settings, General, Audio device information. It is not recommended that you use stereo recording. If you record output from other software such as Windows. Media Player, Real. Player, or Internet player, you need to take. This requires that you know whether the sound. Selecting the audio format for Software recording mode. If you plan to record sound that is already compressed for example, many Internet transmissions are broadcast in MP3 or WMA format then it is recommended that you record in the same format as the sound is being reproduced with. If you are concerned about file size, you can select a sound format with a lower quality. Games American Army. If you plan to record uncompressed sound e. CD then you can either record without conversion if you want to preserve maximum quality or compress it if you want to reduce the file size. You can use either lossy or lossless compression. If the format of the sound source has a higher quality than CD e. DVD audio, you may want to record it in one of the high quality formats which are available only in the Professional, Video Pro and Developer Editions. In Software mode, we recommend that you. After listening to the recorded file, you can determine. After that, record from the same source.

If you want to record in a specific sound format, use on the fly conversion and explicitly indicate the desired format. For example, if you want to put your recording onto an audio CD, you need to select CD quality PCM 4. Hz 1. 6 bit stereo. If you want to create a file with an acceptable sound quality but minimize its size, you can try to record without conversion, and then save the recording using a different target format. After listening to the recorded file, you can determine the desired sound format. Record from the same source and convert it to the determined sound format. It is not feasible to increase the sample frequency or to make a stereo recording out of a mono recording. Also, it is not recommended you change the sample frequency. If you need to use a lower sample frequency to create a smaller file, we recommend reducing the frequency by 2 or 4 times. Poker Card Game Bluff here. This will minimize the loss of quality. Example. A file was created from a recording without format conversion and its format is PCM 2. Hz 1. 6 bit mono. The recommended Save As. PCM 2. Hz 1. 6 bit mono save format unchanged, no loss of quality. Nintendo Ds Biggest Loser Game. MP3 3. 2 k. Bits 2. Hz mono. MP3 2. 4 k. Bits 2. 40. 00 Hz mono. It is not recommended you use the following formats PCM 4.

Another important factor that you need to consider when selecting a recording format are the characteristics of the audio that you plan to record. In general, music requires higher quality formats than speech recordings. For quality recording of music, you should use a sample rate of 4. Hz or higher. For speech recordings of dictaphone quality, it is possible to use 1. Hz. For quality speech recordings or middle quality recordings of music, you can use a sample rate of 2. Hz. If you record an uncompressed sound, you also need to select a bit capacity. For quality recording, a bit capacity would be 1. It is recommended that you use 8 bit format only for speech recordings of dictaphone quality since they have a small dynamic range and a high noise level. The number of channels e. If you plan to record in a compressed format, you can compress speech recordings to a greater degree without losing quality compared with music recordings. For music recordings, only a 5 1. Also, it is recommended that for compression of speech, you use a compression format designed specifically for speech e. DSP True. Speech rather than for music e. MP3. If you record from a source that reproduces high quality sound e. You can use the following table to select the target sound format based on characteristics of sound source.
